    Products Detail

    STD55NH2LLT4 Overview


    The MOSFET's breakdown is called "avalanche break down", and the avalanche energy applied to transistor is rated as 600 mJ (Eas).An op amp's input capacitance is defined as the capacitance between both of its input terminals with either input grounded, and 990pF @ 25V is its maximum input capacitance.The drain current is the maximum continuous current the device can conduct, and this device has 40A continuous drain current (ID).A drainage-to-source breakdown voltage corresponds to the voltage at which a specified value of ID flows, where VGS is 24V, and this device has a drainage-to-source breakdown voltage of 24VV.Drain current refers to the maximum continuous current a device can conduct, and it is 55A.Input capacitance must be charged before drain current conduction can begin, so the turn-off delay time is 13 ns.Peak drain current is 160A, which is the maximum pulsed drain current.An FET transistor's gate-source voltage, VGS, indicates how much voltage is applied across the transistor's gate-source terminal and it can range from 16V to 1.Using drive voltage (4.5V 10V), this device contributes to a reduction in overall power consumption.

    STD55NH2LLT4 Features


    the avalanche energy rating (Eas) is 600 mJ
