SI4446DY-T1-E3 Overview
Op amps with either input grounded have a fixed input capacitance parameter, CI, and this device has a 700pF @ 20V 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 5.2A amps.In this device, the drain-source breakdown voltage is 40V and VGS=40V, so the drain-source breakdown voltage is 40V in this case.A device can conduct a maximum continuous current of [3.9A] according to its drain current.It is [27 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 30A.A turn-on delay time of 7 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 12V.Normally, electrical devices are set to activate all of their operations at threshold voltages, and this transistor's threshold voltage is 1.6V.A device like this reduces its overall power consumption when it uses drive voltage (4.5V 10V).
