STK822 [STMicroelectronics]

STK822 Overview

There is an avalanche breakdown in which energy is applied to the MOSFET to cause it to break down, and this energy is called avalanche energy, and the avalanche energy rating (Eas) is 500 mJ.Op amps with either input grounded have a fixed input capacitance parameter, CI, and this device has a 6060pF @ 25V maximal input capacitance.Devices can conduct a maximum continuous current of 3 amps in the drain area, so the continuous drain current (ID) for this device is 38A amps.In this device, the drain-source breakdown voltage is 25V and VGS=25V, so the drain-source breakdown voltage is 25V in this case.It is [43.5 ns] because it takes time to charge the input capacitance of the device before drain current conduction can begin.As far as peak drain current is concerned, its maximum pulsed current is 152A.Generally, the gate-source voltage (VGS) of a FET transistor is the voltage across its gate-source terminal, which is 16V.Normally, electrical devices are set to activate all of their operations at threshold voltages, and this transistor's threshold voltage is 2.5V.A device like this reduces its overall power consumption when it uses drive voltage (4.5V 10V).
