IRF8313PBF

IRF8313PBF Description

The IRF8313PBF from Infineon Technologies is a logic-level 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 9.7A, it is optimized for low-voltage, high-current operations. The device features a low on-resistance (Rds(on)) of 15.5mΩ at 10V gate drive, ensuring minimal conduction losses. Its logic-level gate threshold (Vgs(th) of 2.35V allows compatibility with 3.3V or 5V microcontroller interfaces, eliminating the need for additional gate drivers. Packaged in an 8-pin SOIC (8SO), it is suitable for surface-mount applications where space and thermal performance are critical.
