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 V0 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:

VF = A + B ⋅ ln(I F )+ C ⋅ I F + D ⋅ I F

The constants, derived by curve fitting software, are given below for hot characteristics. The resulting

values for VF agree with the true device characteristic over a current range, which is limited to that

plotted.
