t_on
Intrinsic turn-on time is negligible (turn-on is dominated by L_S and L_D)
Notes
a. Repetitive rating; pulse width limited by maximum junction temperature (see fig. 11).
b. Pulse width ≤ 300 µs; duty cycle ≤ 2 %.
c. C_oss eff. is a fixed capacitance that gives the same charging time as C_oss while V_DS is rising from 0 to 80 % V_DS.
d. Uses IRF820A/SiHF820A data and test conditions.
