Repetitive rating; pulse width limited by maximum junction temperature (see fig. 11). b. Pulse width ≤ 300 µs; duty cycle ≤ 2 %. c. Coss eff. is a fixed capacitance that gives the same charging time as Coss while VDS is rising from 0 to 80 % VDS. THERMAL RESISTANCE RATINGS PARAMETER SYMBOL TYP. MAX.
