APT40SM120B [Microchip]

APT40SM120B 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 2500 mJ.The maximum input capacitance of this device is 2560pF @ 1000V, because the input capacitance of an op amp is defined as the difference between the input terminals with one input grounded.Continuous drain current (ID) is the maximum continuous current (ID) the device can conduct, and it is 41A.When VGS=1.2kV, and ID flows to VDS at 1.2kVVDS, the drain-source breakdown voltage is 1.2kV in this device.Before drain current conduction can begin, the device's turn-off delay time must be charged up to full capacitance. This value is 32 ns.During device turn-on, the input capacitance must be charged for a period of time before drain current conduction can begin, so its delay time is 10 ns seconds.Single MOSFETs transistor is the voltage across the gate-source terminal of a transistor that determines the gate-source voltage, VGS.This transistor's threshold voltage is 1.7V volts, which indicates that a transistor is ready to perform any of its operations at that voltage.The drain-to-source voltage (Vdss) of this transistor needs to be at 1200V in order to operate.Using drive voltage (20V), this device helps reduce its power consumption.
