APPLICATION N0TES

These surface mountable packages are designed specifically for transient voltage suppression.  The wide leads assure a large sur-

face contact for good heat dissipation, and a low resistance path for surge current flow to ground.  These high speed transient voltage

suppressors can be used to effectively protect sensitive components such as integrated circuits and MOS devices.

A 600W (SMB) device is normally selected when the threat of transients is from lightening-induced transients conducted via external

leads or 1/0 lines.  It is also used to protect against switching transients induced by large coils or industrial motors. 

System impedance at component level in a system is usually high enough to limit the current to within the peak pulse current (I

PP

rating of this series.

RECOMMENDED PAD SIZES

The pad dimensions should be 0.010” (0.25mm) longer than the contact size, in the lead axis. 

This allows a solder fillet to form, see Fig. below. Contact factory for soldering methods.
