SI7421DN-T1-GE3 Overview

In this device, the drain current (ID) is equal to the continuous current transistor can conduct.This device has -30V drain-to-source breakdown voltage, where VDS corresponds to the ID at which a specified value of ID flows and VGS equals -30V.There is no drain current on this device since the maximum continuous current it can conduct is 6.4A.As a result of its turn-off delay time, which is 57 ns, the device has taken time to charge its input capacitance before drain current conduction begins.There is a peak drain current of 30A, its maximum pulsed drain current.Input capacitance charge delays drain current conduction until the time it takes to charge input capacitance reaches 10 ns.Gate-source voltages (VGS) are voltages that fall across the gate-source terminal of FET transistors. VGS is sometimes 20VV.The threshold voltage is the point at which an electrical device activates any one of its operations, which for this transistor is -3V.The transistor must receive a 30V drain to source voltage (Vdss) in order to function.In addition to reducing power consumption, this device uses drive voltage (4.5V 10V).
