De-rating Factor A blocking voltage de-rating factor of 0.13%/°C is applicable to this device for TJ below 25 °C. 3.4. 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. 3.5.

Calculating VF using ABCD Coefficients The on-state characteristic IF vs. VF, on page 7 are represented in two ways: • The well-established V0 and rS tangent used for rating purposes • 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(𝐼𝐹 ) + 𝐶 ∙ 𝐼𝐹 + 𝐷 ∙ √𝐼𝐹 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. 25 °C Coefficients 160 °C Coefficients A 0.7063900 A 0.39067 B 0.01555266 B 0.033410 C 2.926184 x 10-5 C 4.7250 x 10-5 D 10-3 D 3.8157 x 10-3 3.197501 x 3.7.
