Description
📦 Description:
The IRF540N is a popular N-Channel Power MOSFET by Infineon Technologies, capable of switching up to 100V and 33A with very low on-resistance (R<sub>DS(on)</sub> ~44mΩ). Designed for efficiency in DC-DC converters, motor drivers, SMPS, and general-purpose high-speed switching.
This high-speed MOSFET supports logic-level drive and comes in the TO-220 package with a metal tab for heat sinking. Perfect for high-current switching and power control in DIY and professional projects.
