Products Detail

IRFU421 Overview

The maximum input capacitance of this device is 350 pF @ 25 V, because the input capacitance of an op amp is defined as the difference between the input terminals with one input grounded.The drain-to-source voltage (Vdss) of this transistor needs to be at 450 V in order to operate.

IRFU421 Features

a 450 V drain to source voltage (Vdss)
