Vo Threshold Voltage for conduction loss and heatsink calculations. (Tj = 125oC) r Slope resistance IFSM (8.3ms) = IFSM (10ms) x 1.066 I2t (8.3ms) = I2t (10ms) x 0.943 at initial temperature Tj max. A blocking voltage derating factor of 0.13% per degree centigrade is applicable for Tj below 25oC Leaded types, code changes from SP/RP (PHN/R), SN/RN (HHN/R) or SR/RR (PXN/R) .
