IRF740SPBF Description

Short technical summary and product information.

The IRF740SPBF is an N-Channel power MOSFET from Vishay Dale, designed for high-voltage switching applications. It features a drain-source voltage (Vdss) of 400V and a continuous drain current of 10A at 25°C case temperature. The device has a maximum on-resistance of 550mΩ at Vgs=10V and Id=6A, ensuring efficient power conversion. With a gate charge of 63nC, it offers fast switching performance. The MOSFET is avalanche-rated with a single pulse avalanche energy of 520mJ, making it robust for inductive load switching. It is housed in a surface-mount D2PAK (TO-263) package, which provides excellent thermal performance with a maximum power dissipation of 125W at case temperature 25°C. The operating junction temperature range is -55°C to 150°C. This device is suitable for applications such as switch-mode power supplies, DC-DC converters, and motor control circuits.
