IRF840STRLPBF Description

Short technical summary and product information.

The IRF840STRLPBF is a third-generation N-Channel power MOSFET from Vishay Siliconix, 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, with a pulsed current capability of 32A. The device offers a low on-resistance of 850mΩ maximum at Vgs = 10V, ensuring efficient power conversion.

 

This MOSFET is housed in a surface-mount D2PAK (TO-263) package, which provides excellent power dissipation up to 125W at case temperature and 3.1W on a PCB mount. It is characterized by fast switching, repetitive avalanche rating, and a dynamic dV/dt rating of 3.5 V/ns, making it suitable for demanding power circuits.

 

Typical applications include switch-mode power supplies, power factor correction, lighting ballasts, and motor drive circuits. The part is available in tape and reel for automated assembly. The IRF840STRLPBF is specified for operation over a junction temperature range of -55°C to 150°C.
