IRF634 Description

Short technical summary and product information.

The IRF634 is an N-Channel power MOSFET from Vishay Dale, designed for fast switching and rugged performance. It features a maximum drain-source voltage of 250V and continuous drain current of 8.1A at 25°C case temperature. The typical on-resistance is 450mΩ at Vgs=10V and Id=5.1A, ensuring low conduction losses.

 

The device offers advanced characteristics including dynamic dV/dt rating, repetitive avalanche capability, and fast switching performance. Gate charge is typically 41 nC, and input capacitance is 770 pF at 25V Vds. The MOSFET is housed in a through-hole TO-220AB package, suitable for applications requiring up to 74W power dissipation.

 

Designed for industrial and commercial applications, the IRF634 is ideal for power supplies, motor control, and switching regulators. The operating junction temperature range is -55°C to 150°C, providing robust thermal performance. The TO-220AB package allows easy mounting on heatsinks for effective thermal management.
