Notes:

Repetitive rating; pulse width limited by max. junction

temperature.

Limited by TJmax, starting TJ = 25°C, L = 0.23mH

RG = 25Ω, IAS = 25A, VGS =10V. Part not recommended for

use above this value.

ISD ≤ 25A, di/dt ≤ 1580A/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.

When mounted on 1" square PCB (FR-4 or G-10 Material). For recom

mended footprint and soldering techniques refer to application note #AN-994.

Rθ is measured at TJ approximately 90°C.
