IRFS7440PbF/IRFSL7440PbF

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.
