IRF7353D2

IRF7353D2 Description

The IRF7353D2 from Infineon Technologies is an N-channel MOSFET designed for high-efficiency power switching applications. With a drain-to-source voltage (Vdss) of 30V and a continuous drain current (Id) of 6.5A, this device is optimized for low-voltage, high-current scenarios. It features a low on-resistance (Rds(on)) of 29mOhm at 5.8A and 10V gate drive, ensuring minimal conduction losses. The MOSFET integrates a Schottky diode (isolated), enhancing its performance in synchronous rectification and freewheeling applications. Packaged in an 8-pin SOIC (8SO), it is suitable for surface-mount designs.
