14.0 Computer Modelling Parameters
14.1 Calculating VT using ABCD Coefficients
The on-state characteristic IT vs VT, on page 11 is represented in two ways; (i) the well established Vo and
rs 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:

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