Repetitive rating; pulse width limited by
max. junction temperature. ( See fig. 11 )
ISD ≤ 2.5A, di/dt ≤ 270A/s, VDD ≤ V(BR)DSS,
TJ ≤ 150°C
Notes:
Starting T
J = 25°C, L = 45mH
RG = 25, IAS = 2.5A. (See Figure 12)
Pulse width ≤ 300s; duty cycle ≤ 2%.
Coss eff. is a fixed capacitance that gives the same charging time
as Coss while VDS is rising from 0 to 80% VDSS
