FQAF34N25 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 700 mJ.The maximum input capacitance of this device is 2.75pF @ 25V, because the input capacitance of an op amp is defined as the difference between the input terminals with one input grounded.As shown in the table below, the drain current of this device is 21.7A.There is no pulsed drain current maximum for this device based on its rated peak drain current 86.8A.To maintain normal operation, it's recommended that the DS breakdown voltage be kept above 250V.The drain-to-source voltage (Vdss) of this transistor needs to be at 250V in order to operate.Using drive voltage (10V), this device helps reduce its power consumption.
FQAF34N25 Features
