2.0 De-rating Factor
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:
VF = A + B ln(I F ) + C I F + D I F
where IF = instantaneous forward current.
4.0 Reverse recovery ratings
(i) Qra is based on 50% Irm chord as shown in Fig.(a) below.
(ii) Qrr is based on a 150µs integration time.
