Introduction

The M1583VC400-450 fast recovery diode range has controlled reverse recovery characteristics.
Devices with a suffix code (2 letter or letter/digit/letter combination) added to their generic code are not

necessarily subject to the conditions and limits contained in this report.

5.0 Reverse Recovery Loss

The following procedure is recommended for use where it is necessary to include reverse recovery loss.
From waveforms of recovery current obtained from a high frequency shunt (see Note 1) and reverse

voltage present during recovery, an instantaneous reverse recovery loss waveform must be constructed.
Let the area under this waveform be E joules per pulse. A new sink temperature can then be evaluated
from:

The total dissipation is now given by:

This device has a low reverse recovered charge and peak reverse recovery current. When measuring the
charge, care must be taken to ensure that:
