STF3N80K5 [STMicroelectronics]

STF3N80K5 Overview

When a voltage exceeds breakdown voltage of a MOSFET, breakdown phenomena occurs and current flows. It's called ?Avalanche break down?, and the energy applied to the MOSFET is called avalanche energy, and the avalanche energy rating (Eas) is 65 mJ.The input capacitance parameter, CI, is defined as the capacitance between the input terminals of an op amp with either input grounded, and this device's maximal input capacitance is 130pF @ 100V.The drain current is the maximum continuous current the device can conduct, and the continuous drain current (ID) of this device is 2.5A. Drain-source breakdown voltage is the VDS at which a specified value of ID flows, with VGS=800V. And this device has 800V drain to source breakdown voltage.Turn-Off delay time is the time taken to charge the input capacitance of the device before drain current conduction can start, and its turn-off delay time is 20.5 ns.Turn-on delay time is the time taken to charge the input capacitance of the device before drain current conduction can start, and its delay time is 8.5 ns.The gate-source voltage, VGS, of a FET transistor is the voltage that falls across the gate-source terminal of the transistor and its voltage can be 30V.By using drive voltage (10V), this device helps reduce its overall power consumption.
