LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134).

Notes

1. Refer to SOT223 standard mounting conditions.

2. For Schottky barrier diodes thermal run-away has to be considered, as in some applications, the reverse power

losses P

R

 are a significant part of the total power losses. Nomograms for determination of the reverse power losses

R

 and I
