IRF7473 Features

* ive rating; pulse width limited by max. junction temperature. Starting TJ = 25°C, L = 16mH RG = 25Ω, IAS = 4.1A.

* When mounted on 1 inch square copper board Coss eff. is a fixed capacitance that gives the same charging time as Coss while VDS is rising from 0 to 80% VDSS ISD ≤ 4.1A,
