IRF540 Description

Short technical summary and product information.

The IRF540 is an N-Channel Power MOSFET manufactured by Vishay Siliconix, part of the third-generation Power MOSFET family. It is designed for fast switching and rugged performance in commercial and industrial applications.

 

Key electrical specifications include a maximum drain-source voltage (Vdss) of 100V, continuous drain current of 28A at Tc=25°C, and pulsed drain current of 110A. The on-resistance is typically 77mΩ maximum at Vgs=10V and Id=17A. Gate charge is 72nC maximum at Vgs=10V, and input capacitance is 1700pF at Vds=25V. The device is avalanche rated with a single pulse energy of 230mJ.

 

The IRF540 is packaged in a TO-220-3 (TO-220AB) through-hole package, suitable for up to 150W power dissipation at Tc=25°C. Operating junction temperature range is -55°C to 175°C. The package offers low thermal resistance and ease of mounting.

 

These characteristics make the IRF540 suitable for switched-mode power supplies, DC-DC converters, motor control circuits, and general-purpose power switching applications. The simple drive requirements and fast switching performance enable efficient power management.
