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:

[]

Where k = 0.2314 (°C/W)/s

E

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

R

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:

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

(c) Measurement of reverse recovery waveform should be carried out with an appropriate critically
damped snubber, connected across diode anode to cathode. The formula used for the calculation of this

Where: Vr= Commutating source voltage

6.0 Snubber Components

When selecting snubber components, care must be taken not to use excessively large values of snubber
capacitor or excessively small values of snubber resistor. Such excessive component values may lead to
device damage due to the large resultant values of snubber discharge current. If required, please consult
the factory for assistance.
