FDB9403-F085 Description

Short technical summary and product information.

The FDB9403-F085 is an N-Channel Power Trench MOSFET from On Semiconductor, designed for high-efficiency switching applications. It features a maximum drain-source voltage of 40V and a continuous drain current rating of 110A at Tc=25°C. The device achieves an ultra-low on-resistance of 1.2mΩ maximum (1.0mΩ typical) at Vgs=10V and Id=80A, minimizing conduction losses.

 

Key electrical characteristics include a total gate charge of 213nC maximum (164nC typical) and an input capacitance of 12700pF, enabling fast switching. The MOSFET is rated for single-pulse avalanche energy of 968mJ, ensuring robustness in inductive load switching. Operating temperature range is -55°C to 175°C junction temperature, with a thermal resistance junction-to-case of 0.45°C/W.

 

Housed in a surface-mount TO-263AB (D²Pak) package with gull-wing leads, the device is suitable for automated assembly. It is qualified to AEC-Q101 automotive standard and is RoHS compliant. Typical applications include automotive engine control, powertrain management, solenoid and motor drivers, electronic steering, and primary switching for 12V systems.
