5.2 Calculating V F using ABCD Coefficients
The on-state characteristic I F vs. V F , on page 6 is represented in two ways;
(i) the well established V T0 and r T tangent used for rating purposes and
(ii) a set of constants A, B, C, D, forming the coefficients of the representative equation for V F in
terms of I F given below:
V F = A + B ? ln ( I F ) + C ? I F + D ? I F
The constants, derived by curve fitting software, are given below for both hot and cold characteristics.
The resulting values for V F agree with the true device characteristic over a current range, which is
limited to that plotted.
