IRF840LCPBF Description

Short technical summary and product information.

The IRF840LCPBF is an N-Channel power MOSFET designed for high-voltage switching applications. It features a maximum drain-source voltage (Vds) of 500V and a continuous drain current (Id) of 8A at 25°C case temperature. The device utilizes MOSFET (Metal Oxide) technology and offers a low on-resistance of 850mOhm at 4.8A and 10V gate drive.

 

This MOSFET is rated for a maximum power dissipation of 125W at 25°C case temperature and can operate over a junction temperature range of -55°C to 150°C. It includes enhanced gate drive capability with a maximum gate-source voltage of ±30V and a gate threshold voltage of 4V at 250µA drain current. The device also features ultra low gate charge (39 nC typical) for reduced switching losses.

 

The IRF840LCPBF is supplied in a TO-220AB (TO-220-3) through-hole package, suitable for PCB mounting. It is lead (Pb)-free and RoHS compliant per the datasheet.
