STF40N20 [STMicroelectronics]

STF40N20 Overview

Op amps with either input grounded have a fixed input capacitance parameter, CI, and this device has a 2500pF @ 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 40A amps.In this device, the drain-source breakdown voltage is 200V and VGS=200V, so the drain-source breakdown voltage is 200V in this case.It is [74 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 160A.A turn-on delay time of 20 ns indicates the time it takes for the input capacitance of the device to charge before drain current conduction starts.Generally, the gate-source voltage (VGS) of a FET transistor is the voltage across its gate-source terminal, which is 20V.A device like this reduces its overall power consumption when it uses drive voltage (10V).
