Notes:
 Repetitive rating; pulse width limited by max. junction
temperature.
‚ Limited by TJmax, starting TJ = 25°C, L = 0.12mH
RG = 50
Ω, IAS = 75A, VGS =10V. Part not recommended for use
above this value.
ƒ ISD ≤ 75A, di/dt ≤ 890A/μs, VDD ≤ V(BR)DSS, TJ ≤ 175°C.
„ Pulse width ≤ 400μs; duty cycle ≤ 2%.
… Coss eff. (TR) is a fixed capacitance that gives the same charging
time as Coss while VDS is rising from 0 to 80% VDSS.
