APPLICATION NOTE — ZENER VOLTAGE

Since the actual voltage available from a given zener diode

is temperature dependent, it is necessary to determine junc-

tion temperature under any set of operating conditions in order

to calculate its value. The following procedure is recom-

mended:

Lead Temperature, TL, should be determined from:

TL = 

θ

LAPD + TA.

θ

LA is the lead-to-ambient thermal resistance (

°

C/W) and PD is

the power dissipation. The value for 

θ

LA will vary and depends

on the device mounting method. 

θ

LA is generally 30 to 40

°

C/W

for the various clips and tie points in common use and for

printed circuit board wiring.

The temperature of the lead can also be measured using a

thermocouple placed on the lead as close as possible to the tie

point. The thermal mass connected to the tie point is normally

large enough so that it will not significantly respond to heat

surges generated in the diode as a result of pulsed operation

once steady-state conditions are achieved. Using the mea-

sured value of TL, the junction temperature may be deter-

mined by:

TJ = TL + 

TJL.

TJL is the increase in junction temperature above the lead

temperature and may be found from Figure 2 for dc power:

TJL = 

θ

JLPD.

For worst-case design, using expected limits of IZ, limits of

PD and the extremes of TJ(

TJ) may be estimated. Changes in

voltage, VZ, can then be found from:

V = 

θ

VZTJ.

θ

VZ, the zener voltage temperature coefficient, is found from

Figures 4 and 5.

Under high power-pulse operation, the zener voltage will

vary with time and may also be affected significantly by the

zener resistance. For best regulation, keep current excursions

as low as possible.

Surge limitations are given in Figure 7. They are lower than

would be expected by considering only junction temperature,

as current crowding effects cause temperatures to be ex-

tremely high in small spots, resulting in device degradation

should the limits of Figure 7 be exceeded.

*Indicates JEDEC Registered Data

NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION

Tolerance designation — Device tolerances of 

±

5% are indicated by a “B” suffix, 

±

2% by a

“C” suffix, 

±

1% by a “D” suffix.

NOTE 2.

This data was calculated using nominal voltages. The maximum current handling capability

on a worst case basis is limited by the actual zener voltage at the operating point and the pow-

er derating curve.

NOTE 3.

ZZT and ZZK are measured by dividing the ac voltage drop across the device by the ac current

applied. The specified limits are for IZ(ac) = 0.1 IZ(dc) with the ac frequency = 1.0 kHz.

NOTE 4.

Nominal Zener Voltage (VZ) is measured with the device junction in thermal equilibrium at the

lead temperature of 30

°

±

1

°

C and 3/8

 lead length.

NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION

The type numbers shown have a standard tolerance of 

±

5% on the nominal zener voltage.

NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT

Nominal Zener Voltage is measured with the device junction in the thermal equilibrium with

ambient temperature of 25

°

C.

NOTE 3. ZENER IMPEDANCE (ZZT) DERIVATION

The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-

rent having an rms value equal to 10% of the dc zener current (IZT) is superimposed on IZT.

NOTE 4. MAXIMUM ZENER CURRENT RATINGS (IZM)

Maximum zener current ratings are based on maximum zener voltage of the individual units.

NOTE 5. REVERSE LEAKAGE CURRENT IR

Reverse leakage currents are guaranteed and are measured at VR as shown on the table.

NOTE 6. SPECIAL SELECTORS AVAILABLE INCLUDE:

A) Tighter voltage tolerances. Contact your nearest Motorola representative for more infor-

mation.

NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION

The “B” suffix type numbers listed are 

±

5% tolerance of nominal VZ.

NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT

Nominal zener voltage is measured with the device junction in thermal equilibrium with ambi-

ent temperature of 25

°

C.

NOTE 3. ZENER IMPEDANCE (ZZ) DERIVATION

The zener impedance is derived from the 60 Hz ac voltage, which results when an ac current

having an rms value equal to 10% of the dc zener current (IZT) is superimposed on IZT.

NOTE 4. REVERSE LEAKAGE CURRENT IR

Reverse leakage currents are guaranteed and are measured at VR as shown on the table.

NOTE 5. MAXIMUM REGULATOR CURRENT (IZM)

The maximum current shown is based on the maximum voltage of a 

±

5% type unit, therefore,

it applies only to the “B” suffix device. The actual IZM for any device may not exceed the value

of 400 milliwatts divided by the actual VZ of the device.

NOTE 6. MAXIMUM REGULATION FACTOR (

VZ)

VZ is the maximum difference between VZ at IZT and VZ at IZL measured with the device

junction in thermal equilibrium.

Motorola TVS/Zener Device Data

6-118

500 mW DO-35 Glass Data Sheet

APPLICATION NOTE

Since the actual voltage available from a given zener diode

is temperature dependent, it is necessary to determine junc-

tion temperature under any set of operating conditions in order

to calculate its value. The following procedure is recom-

mended:

Lead Temperature, TL, should be determined from:

TL = 

θ

LAPD + TA.

θ

LA is the lead-to-ambient thermal resistance (

°

C/W) and PD is

the power dissipation. The value for 

θ

LA will vary and depends

on the device mounting method. 

θ

LA is generally 30 to 40

°

C/W

for the various clips and tie points in common use and for

printed circuit board wiring.

The temperature of the lead can also be measured using a

thermocouple placed on the lead as close as possible to the tie

point. The thermal mass connected to the tie point is normally

large enough so that it will not significantly respond to heat

surges generated in the diode as a result of pulsed operation

once steady-state conditions are achieved. Using the mea-

sured value of TL, the junction temperature may be deter-

mined by:

TJ = TL + 

TJL.

TJL is the increase in junction temperature above the lead

temperature and may be found as follows:

TJL = 

θ

JLPD.

θ

JL may be determined from Figure 3 for dc power condi-

tions. For worst-case design, using expected limits of IZ, limits

of PD and the extremes of TJ(

TJ) may be estimated. Changes

in voltage, VZ, can then be found from:

V = 

θ

VZ 

TJ.

θ

VZ, the zener voltage temperature coefficient, is found from

Figure 2.

Under high power-pulse operation, the zener voltage will

vary with time and may also be affected significantly by the

zener resistance. For best regulation, keep current excursions

as low as possible.

Surge limitations are given in Figure 5. They are lower than

would be expected by considering only junction temperature,

as current crowding effects cause temperatures to be ex-

tremely high in small spots, resulting in device degradation

should the limits of Figure 5 be exceeded.

APPLICATION NOTE

Since the actual voltage available from a given zener diode

is temperature dependent, it is necessary to determine junc-

tion temperature under any set of operating conditions in order

to calculate its value. The following procedure is recom-

mended:

Lead Temperature, TL, should be determined from:

TL = 

θ

LA PD + TA

θ

LA is the lead-to-ambient thermal resistance (

°

C/W) and

PD is the power dissipation. The value for 

θ

LA will vary and

depends on the device mounting method. 

θ

LA is generally

30–40

°

C/W for the various clips and tie points in common

use and for printed circuit board wiring.

The temperature of the lead can also be measured using a

thermocouple placed on the lead as close as possible to the tie

point. The thermal mass connected to the tie point is normally

large enough so that it will not significantly respond to heat

surges generated in the diode as a result of pulsed operation

once steady-state conditions are achieved. Using the mea-

sured value of TL, the junction temperature may be deter-

mined by:

TJ = TL + 

TJL

TJL is the increase in junction temperature above the lead

temperature and may be found from Figure 2 for a train of

power pulses (L = 3/8 inch) or from Figure 10 for dc power.

TJL = 

θ

JL PD

For worst-case design, using expected limits of IZ, limits of

PD and the extremes of TJ (

TJ) may be estimated. Changes

in voltage, VZ, can then be found from:

V = 

θ

VZ 

TJ

θ

VZ, the zener voltage temperature coefficient, is found from

Figures 5 and 6.

Under high power-pulse operation, the zener voltage will

vary with time and may also be affected significantly by the

zener resistance. For best regulation, keep current excursions

as low as possible.

Data of Figure 2 should not be used to compute surge capa-

bility. Surge limitations are given in Figure 3. They are lower

than would be expected by considering only junction tempera-

ture, as current crowding effects cause temperatures to be ex-

tremely high in small spots resulting in device degradation

should the limits of Figure 3 be exceeded.

NOTE 1. TOLERANCES

Suffix 5 indicates 5% tolerance. Any other tolerance will be considered as a special device.

NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT

Motorola guarantees the zener voltage when measured at 40 ms 

±

10 ms 3/8

 from the diode

body, and an ambient temperature of 25

°

C (+8

°

C, –2

°

C)

NOTE 3. ZENER IMPEDANCE (ZZ) DERIVATION

The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-

rent having an rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed

on IZT or IZK.

NOTE 4. SURGE CURRENT (ir) NON-REPETITIVE

The rating listed in the electrical characteristics table is maximum peak, non-repetitive, re-

verse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second dura-

tion superimposed on the test current, IZT, per JEDEC standards, however, actual device ca-

pability is as described in Figure 3 of General Data sheet for Surmetic 30s.

NOTE 5. SPECIAL SELECTIONS AVAILABLE INCLUDE:

Nominal zener voltages between those shown. Tight voltage tolerances such as 

±

1% and

±

2%. Consult factory.

NOTE 1. TOLERANCE AND TYPE NUMBER DESIGNATION

The JEDEC type numbers shown indicate a tolerance of 

±

5%.

NOTE 2. ZENER VOLTAGE (VZ) AND IMPEDANCE (ZZT & ZZK)

Test conditions for zener voltage and impedance are as follows: IZ is applied 40 

±

 10 ms prior

to reading. Mounting contacts are located 3/8

 to 1/2

 from the inside edge of mounting clips

to the body of the diode. (TA = 25

°

C +8, –2

°

C).

NOTE 3. SURGE CURRENT (ir)

Surge current is specified as the maximum allowable peak, non-recurrent square-wave cur-

rent with a pulse width, PW, of 8.3 ms. The data given in Figure 6 may be used to find the

maximum surge current for a square wave of any pulse width between 1ms and 1000 ms by

plotting the applicable points on logarithmic paper. Examples of this, using the 3.3 V and

200 V zeners, are shown in Figure 7. Mounting contact located as specified in Note 3. (TA =

25

°

C +8, –2

°

C.)

NOTE 4. VOLTAGE REGULATION (

VZ)

Test conditions for voltage regulation are as follows:  VZ measurements are made at 10% and

then at 50% of the IZ max value listed in the electrical characteristics table. The test current

time duration for each VZ measurement is 40 

±

 10 ms. (TA = 25

°

C +8, –2

°

C). Mounting contact

located as specified in Note 2.

NOTE 5. MAXIMUM REGULATOR CURRENT (IZM)

The maximum current shown is based on the maximum voltage of a 5% type unit, therefore,

it applies only to the B-suffix device. The actual IZM for any device may not exceed the value

of 5 watts divided by the actual VZ of the device. TL = 75

°

C at 3/8

 maximum from the device

APPLICATION NOTE

Since the actual voltage available from a given zener diode

is temperature dependent, it is necessary to determine junc-

tion temperature under any set of operating conditions in order

to calculate its value. The following procedure is recom-

mended:

Lead Temperature, TL, should be determined from:

TL = 

θ

LA PD + TA

θ

LA is the lead-to-ambient thermal resistance and PD is the

power dissipation.

Junction Temperature, TJ, may be found from:

TJ = TL + 

TJL

TJL is the increase in junction temperature above the lead

temperature and may be found from Figure 4 for a train of

power pulses or from Figure 5 for dc power.

TJL = 

θ

JL PD

For worst-case design, using expected limits of IZ, limits of

PD and the extremes of TJ (

TJ) may be estimated. Changes

in voltage, VZ, can then be found from:

V = 

θ

VZ 

TJ

θ

VZ, the zener voltage temperature coefficient, is found from

Figures 2 and 3.

Under high power-pulse operation, the zener voltage will

vary with time and may also be affected significantly by the

zener resistance. For best regulation, keep current excursions

as low as possible.

Data of Figure 4 should not be used to compute surge capa-

bility. Surge limitations are given in Figure 6. They are lower

than would be expected by considering only junction tempera-

ture, as current crowding effects cause temperatures to be ex-

tremely high in small spots resulting in device degradation

should the limits of Figure 6 be exceeded.
