2.0 Extension of Voltage Grades
This report is applicable to other voltage grades when supply has been agreed by Sales/Production.
3.0 De-rating Factor
A blocking voltage de-rating factor of 0.13%/°C is applicable to this device for Tj below 25°C.
4.0 Snubber Components
When selecting snubber components, care must be taken not to use excessively large values of snubber
capacitor or excessively small values of snubber resistor. Such excessive component values may lead to
device damage due to the large resultant values of snubber discharge current. If required, please consult
the factory for assistance.

5.2 Calculating VF using ABCD Coefficients
The on-state characteristic IF vs. VF, on page 5 is represented in two ways;
(i)
the well established V0 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 VF in
terms of IF given below:
VF = 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 VF agree with the true device characteristic over a current range, which is limited to
that plotted.
