IRF540 N-Channel MOSFET – 100V 28A

The IRF540 is a high-performance N-channel power MOSFET designed for medium- to high-power switching applications. It supports a drain-source voltage of up to 100V and continuous drain current up to 28A under proper cooling conditions. With a low on-resistance of approximately 0.077?, the IRF540 provides efficient conduction with reduced heat generation and lower power loss. Its fast switching performance and rugged avalanche capability make it ideal for motor control, DC-DC converters, power supplies, inverters, and load switching circuits.
