IRF540 Description

Short technical summary and product information.

The IRF540 is an N-Channel enhancement-mode power MOSFET designed for high efficiency power switching applications. It features a maximum drain-source voltage of 100V and a continuous drain current of 28A at 25°C case temperature. The device offers a low on-resistance of 77 mOhm at 10V gate drive, enabling reduced conduction losses. With a gate charge of 72 nC and fast switching characteristics, it is suitable for moderate frequency operation. The MOSFET can dissipate up to 150W of power and operates over a junction temperature range of -55°C to 175°C. It is built with third-generation MOSFET technology for ruggedness and ease of paralleling. The part is housed in a standard TO-220AB through-hole package, which is widely used in commercial and industrial power circuits. Typical applications include switch-mode power supplies, DC-DC converters, motor control drivers, and general purpose power switching.
