Product details

The IRF540ZL is an International Rectifier HEXFET® N-channel power MOSFET in a TO-262 through-hole package.

For an existing BOM, verify the replacement's Rds(on) and gate charge against your thermal and switching budget before committing.

Thermal and mounting — through-hole TO-262

The TO-262 (I²Pak) package is a through-hole variant with long leads, designed for heatsink mounting through the tab. Maximum power dissipation is 92 W at case temperature — that figure assumes an infinite heatsink; real-world derating follows the junction-to-case thermal resistance. For a 36 A continuous load, the tab must be bolted to a heatsink with adequate thermal interface material; free-air operation is limited to much lower current.

Frequently asked questions

What is the replacement for IRF540ZL?

For a new design, evaluate active 100 V N-channel MOSFETs in TO-220 or D²Pak from the same HEXFET family, but verify pin compatibility — the TO-262 lead form is unique.
