9.3 Calculating VT using ABCD Coefficients
The on-state characteristic IT vs. VT, on page 6 is represented in two ways;
(i) the well established VT0 and rT tangent used for rating purposes and
(ii) a set of constants A, B, C, D, forming the coefficients of the representative equation for VT in
terms of IT given below:
VT = A + B ln(IT ) + C IT + D IT
The constants, derived by curve fitting software, are given below for the hot and cold characteristics. The
resulting values for VT agree with the true device characteristic over a current range, which is limited to
that plotted.
25°C Coefficients
A 2.923185
B -0.3210737
C 0.868939×10-4
D 0.03709766
125°C Coefficients
A 2.206732
B -0.1958308
C 1.169098×10-3
D 0.03090623
10.0 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.
11.0 Reverse recovery ratings
(i) Qra is based on 50% Irm chord as shown in Fig. 1
(ii) Qrr is based on a 150µs integration time i.e.
150 µs
Qrr = irr .dt
0
(iii)
K Factor = t1

12.0 Duty cycle lines
The 100% duty cycle is represented on the frequency ratings by a straight line. Other duties can be
included as parallel to the first.
