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 ofthe expression for the forward characteristic given below:

FFFF IDICIBAV ⋅+⋅+⋅+= )ln(

where IF = instantaneous forward current.

4.0 Reverse recovery ratings

(i) Qra is based on 50% Irm chord as shown in Fig.(a) below.

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 reversevoltage 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 evaluatedfrom:

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.

RthJK = 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 thecharge, care must be taken to ensure that:

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

(b) A suitable, polarised, clipping circuit must be connected to the input of the measuring oscilloscopeto 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 criticallydamped snubber, connected across diode anode to cathode. The formula used for the calculation of thissnubber is shown below:

⋅= 42

Where: Vr = Commutating source voltageCS = Snubber capacitanceR = Snubber resistance

6.0 Snubber Components

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

7.2 Calculation of VF using ABCD Coefficients

The forward characteristic IF Vs VF, on page 6 is represented in two ways;(i) the well established VT0 and rT tangent used for rating purposes and((iiii)) a set of constants A, B, C, and D forming the coefficients of the representative equation for VF in

terms of IF given below:

The constants, derived by curve fitting software, are given in this report for both hot and coldcharacteristics. The resulting values for VF agree with the true device characteristic over a current range,which is limited to that plotted.

8.0 Frequency Ratings

The curves illustrated in figures 8 to 16 are for guidance only and are superseded by the maximum ratingsshown on page 1.

9.0 Square wave ratings

These ratings are given for load component rate of rise of forward current of 100 and 500 A/µs.

10.0 Duty cycle lines

The 100% duty cycle is represented on all the ratings by a straight line. Other duties can be included asparallel to the first.
