5.2 Calculating V
T
using ABCD coefficients
N1063xx53xxx to N1063xx65xxx
The on-state characteristic I
T
vs V
T
, on Fig. 9, is represented in two ways; (i) the well
established V
0
and r
S
tangent and (ii) a set of constants A, B, C, D, forming the coefficients of
the representative equation for V
T
in terms of I
T
given below:

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