5.2 Calculating VF using ABCD Coefficients
The on-state 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
(ii) a set of constants A, B, C, 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 below for both hot and cold characteristics.
The resulting values for VF agree with the true device characteristic over a current range, which is
limited to that plotted.
