14.0 Computer Modelling Parameters
14.1 Calculating VT using ABCD Coefficients
The on-state characteristic IT vs VT, on page 8 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 and cold characteristics
where possible. The resulting values for VT agree with the true device characteristic over a current range,
which is limited to that plotted.
