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. 5.0 Computer Modelling Parameters 5.1 Device Dissipation Calculations 2 I AV = WAV = 2 − VT 0 + VT 0 + 4 ⋅ ff ⋅ rT ⋅WAV 2 ⋅ ff 2 ⋅ rT and: ∆T Rth ∆T = T j max − TK Where VT0=0.926V, rT=0.739mΩ, Rth = Supplementary thermal impedance, see table below and ff = Form factor, see table below.

The resulting values for VF agree with the true device characteristic over a current range, which is limited to that plotted. 25°C Coefficients 150°C Coefficients A 0.7795642 A 0.6340984 B 0.04590695 B 0.04112559 -4 C 5.72979×10 -3 D 5.790022×10 C 4.64903×10 D 2.19035×10 -4 -3 6.0 Reverse recovery ratings (i) Qra is based on 50% Irm chord as shown in Fig. 1 Fig. 1 150 µs (ii) Qrr is based on a 150µs integration time i.e. Qrr = ∫i rr .dt 0 (iii) K Factor = t1 t2 Provisional Data Sheet.
