Vishay Siliconix SI4122DY-T1-GE3

SI4122DY-T1-GE3 Overview
CI refers to the capacitance between two input terminals on an op amp with either input grounded, and this device's maximum input capacitance is 4200pF @ 20V.In this device, the drain current (ID) is equal to the continuous current transistor can conduct.This device has 40V drain-to-source breakdown voltage, where VDS corresponds to the ID at which a specified value of ID flows and VGS equals 40V.As a result of its turn-off delay time, which is 45 ns, the device has taken time to charge its input capacitance before drain current conduction begins.Input capacitance charge delays drain current conduction until the time it takes to charge input capacitance reaches 42 ns.Gate-source voltages (VGS) are voltages that fall across the gate-source terminal of FET transistors. VGS is sometimes 25VV.The threshold voltage is the point at which an electrical device activates any one of its operations, which for this transistor is 2.5V.In addition to reducing power consumption, this device uses drive voltage (4.5V 10V).
