N-Channel 3Ohm @ 1.3A, 10V ±20V 350 pF @ 25 V 19 nC @ 10 V 450 V TO-251-3 Short Leads, IPak, TO-251AA
IRFU421 Overview
This type of breakdown is known as "avalanche breakdown", and the energy applied to the MOSFET is called avalanche energy, and the avalanche energy rating (Eas) is 210 mJ.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.There is no pulsed drain current maximum for this device based on its rated peak drain current 8 A.To maintain normal operation, it's recommended that the DS breakdown voltage be kept above 450 V.The drain-to-source voltage (Vdss) of this transistor needs to be at 450 V in order to operate.
IRFU421 Features
the avalanche energy rating (Eas) is 210 mJ
based on its rated peak drain current 8 A.
a 450 V drain to source voltage (Vdss)
