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 T_jbelow 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 V_Fusing ABCD Coefficients

The on-state characteristic I_Fvs. V_F, on page 6 is represented in two ways;

(i)

(ii)

the well established V_T0and r_Ttangent used for rating purposes and

a set of constants A, B, C, D, forming the coefficients of the representative equation for V_Fin

terms of I_Fgiven below:

V_F= 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 V_Fagree with the true device characteristic over a current range, which is limited

to that plotted.
