IRF540N Datasheet. Specs and Replacement
The IRF540N is an N-channel MOSFET widely used in power electronics for switching and amplification. Featuring a low on-resistance of 44mΩ and a high current handling capability up to 33A, it efficiently controls loads in applications such as motor drivers, power supplies, inverters. Its maximum drain-to-source voltage (V_DS) is 100V, with a gate threshold voltage (V_GS(th)) between 2–4V, allowing easy interfacing with logic-level circuits. The device offers fast switching times and rugged thermal performance, making it ideal for high-speed and high-power circuits. Proper heat sinking is recommended to maintain reliability under heavy loads.
