Intrinsic turn-on time is negligible (turn-on is dominated by LS+LD)
Notes:
Repetitive rating; pulse width limited by
max. junction temperature. (See fig. 11).
Starting TJ = 25°C, L = 0.11mH
RG = 25Ω, IAS = 101A. (See Figure 12).
ISD ≤ 101A, di/dt ≤ 210A/µs, VDD ≤ V(BR)DSS
TJ ≤ 175°C
ꢀCoss eff. is a fixed capacitance that gives the same charging time
as Coss while VDS is rising from 0 to 80% VDSS
.
Calculated continuous current based on maximum allowable
junction temperature. Package limitation current is 75A.
Limited by TJmax , see Fig.12a, 12b, 15, 16 for typical repetitive
avalanche performance.

Pulse width ≤ 400µs; duty cycle ≤ 2%.
