MOSFET Calculator

MOSFET Switching Loss Calculator

Estimate MOSFET switching loss from voltage, current, rise/fall time and switching frequency.

MOSFET Switching Loss Calculator Formula

Psw = 0.5 x V x I x (tr + tf) x f

Useful for motor drivers, LED drivers, DC/DC converters, power switches and MCU-controlled loads.

Design note

Always check MOSFET datasheet limits, thermal resistance, gate charge, safe operating area and PCB copper area.
