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 rec overy loss waveform must be constructed. Let the area under this waveform be E joules per pulse. A new sink tem perature can then be evaluated from:

)(

Where k = 0.2314 (°C/W)/s

= Area under reverse loss waveform per pulse in joules (W.s.) = Rated frequency in Hz at the original sink temperature.

The total dissipation is now given by:

This device has a low reverse rec overed char ge and peak revers e rec overy current. When m easur ing the charge, care must be taken to ensure that:

to avoid overloading the internal amplifiers by the relatively high amplitude forward current signal.

6.0 Snubber Components When selecting snubber components, care m ust be taken not to us e excessively large values of snubber

capacitor or excessively sm all values of snubber re sistor. Such exc essive com ponent values may lead to device damage due to the large resultant values of snubber dis charge current. If required, please cons ult the factory for assistance.
