IRF840FI Description

Short technical summary and product information.

The STMicroelectronics IRF840FI is an N-Channel Power MOSFET housed in a TO-220AB package. It features a maximum drain-source voltage (Vds) of 500V and a low on-resistance (Rds(on)) of 0.85 Ohms at a gate-source voltage (Vgs) of 10V. The device has a continuous drain current (Id) of 4.5A when Vgs is 10V. Its typical gate charge (Qg) is 35nC.

 

This power MOSFET is suitable for applications requiring efficient switching and power handling. The TO-220AB package is designed for through-hole mounting, facilitating integration into circuit boards. Its electrical characteristics make it a reliable component for power management circuits and other electronic designs.

 

Key specifications include a 500V breakdown voltage and a low static resistance, contributing to reduced power loss during operation. The typical gate charge indicates the drive requirements for the MOSFET.
