IRFI540N Description

Short technical summary and product information.

The IRFI540N from Vishay Dale is an N-Channel HEXFET Power MOSFET designed for efficient power applications. It features a high breakdown voltage of 100V and a continuous drain current rating of 20A at 25°C.

 

This MOSFET offers a low on-resistance of 0.052 Ohms at 11A and 10V gate-source voltage, contributing to reduced power loss. The device is rated for a maximum power dissipation of 54W at 25°C.

 

Packaged in a TO-220 FULLPAK, the IRFI540N provides advanced process technology and an isolated package. This design simplifies integration by eliminating the need for additional insulating hardware in commercial-industrial applications. The moulding compound offers high isolation capability and low thermal resistance between the tab and an external heatsink.

 

Key electrical parameters include a gate threshold voltage between 2.0V and 4.0V, and a gate-to-source voltage range of ±20V. The operating junction and storage temperature range is from -55°C to +175°C.
