Notes
a. Repetitive rating; pulse width limited by maximum junction temperature.
b. VDD = 50 V, starting TJ = 25 °C, L = 2.3 mH, Rg = 25 , IAS = 13 A.
c. 1.6 mm from case.
d. ISD  ID, starting TJ = 25 °C.

Notes
a. Coss(er) is a fixed capacitance that gives the same energy as Coss while VDS is rising from 0 % to 80 % VDS.
b. Coss(tr) is a fixed capacitance that gives the same charging time as Coss while VDS is rising from 0 % to 80 % VDS.
