A blocking voltage de-rating factor of 0.13% per °C is applicable to this device for Tj below 25°C.

3.0 ABCD Constants

These constants (applicable only over current range of VF characteristic in Figure 1) are the coefficients of
the expression for the forward characteristic given below:

where IF = instantaneous forward current.

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.

NOTE 1 - Reverse Recovery Loss by Measurement

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

(a) AC coupled devices such as current transformers are not affected by prior passage of high

amplitude forward current.

(b) A suitable, polarised, clipping circuit must be connected to the input of the measuring oscilloscope

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

)()(

RfkETT ⋅+⋅−=

)()( JKthMAXjSINK

(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
snubber is shown below:

Where: Vr= Commutating source voltage

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.
