Such excessive component values may lead to device damage due to the large resultant values of snubber discharge current.

The resulting values for VF agree with the true device characteristic over a current range, which is limited to that plotted. 25C Coefficients 150C Coefficients A 0.46164273 A 0.435837127 B 0.1048225 B 0.06435749 C 1.84243x10 D -2.353947x10 -4 C 1.6116x10 D -7.48063x10 Data Sheet.
