1.0 De-rating Factor
A blocking voltage de-rating factor of 0.13% per °C is applicable to this device for Tj below 25°C.
2.0 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: FFFF IDICIBAV +++= )ln( where IF = instantaneous forward current.

4.0 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 eval uated from: )()( HsJthMAXJSINK RfkETT −+−= Where k = 0.2314 (°C/W)/s E = Area under reverse loss waveform per pulse in joules (W.s.) f = Rated frequency in Hz at the original sink temperature. Rth(J-Hs) = d.c. thermal resistance (°C/W) The total dissipation is now given by: fEWW originaltot += )()( 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. (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: dtdiC VR s r = 42 Where: Vr = Commutating source voltage CS = Snubber capacitance R = Snubber resistance
