IRF840SPBF Description

Short technical summary and product information.

The IRF840SPBF is an N-Channel Power MOSFET from Vishay Dale, designed for high-voltage switching applications. It features a maximum drain-source voltage of 500V and a continuous drain current of 8A at 25°C case temperature. The device offers a low maximum on-resistance of 850mΩ at a gate-source voltage of 10V and a drain current of 4.8A.

 

This MOSFET utilizes third-generation power MOSFET technology, providing fast switching and ruggedized device design. It is rated for repetitive avalanche and has a dynamic dV/dt rating. The total gate charge is 63nC maximum at 10V, with gate-source charge of 9.3nC and gate-drain charge of 32nC typical.

 

The IRF840SPBF is housed in a D2PAK (TO-263) surface-mount package, which offers low internal connection resistance and can dissipate up to 125W at 25°C case temperature. It is suitable for high-current applications and is available in tape and reel packaging. The device operates over a junction temperature range of -55°C to 150°C.
