Intrinsic turn-on time is negligible (turn-on is dominated by LS and LD)
Notes
a. 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 givs the same charging time as Coss while VDS is rising from 0 to 80 % VDS.
