Notes:
Calculated continuous current based on maximum allowable junction
temperature. Bond wire current limit is 120A. Note that current
limitations arising from heating of the device leads may occur with
some lead mounting arrangements. (Refer to AN-1140)
Repetitive rating; pulse width limited by max. junction
temperature.
Limited by TJmax, starting TJ = 25°C, L = 0.048mH
RG = 50Ω, IAS = 100A, VGS =10V.
ISD ≤ 100A, di/dt ≤ 1330A/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.
Coss eff. (ER) is a fixed capacitance that gives the same energy as
Coss while VDS is rising from 0 to 80% VDSS.
Rθ is measured at TJ approximately 90°C.
Limited by TJmax starting TJ = 25°C, L= 1mH, RG = 50Ω, IAS = 34A, VGS =10V.
