IRF540 MOSFET Overview
The IRF540 is an N-channel MOSFET designed for high-speed switching applications. It operates with low gate drive power, making it ideal for power management circuits. The MOSFET has a high current capacity (up to 33A) and a low on-state resistance (R_DS(on) of 44mΩ), ensuring efficiency in power conversion applications. It has a maximum voltage rating of 100V, making it suitable for medium-power applications. The IRF540 is widely used in motor controllers, DC-DC converters, and power supplies.
