FDS9945 Description

Short technical summary and product information.

The FDS9945 is a dual N-channel MOSFET manufactured by On Semiconductor. It features two N-channel MOSFETs in a single 8-SOIC package, each rated for a drain-to-source voltage of 60 V and a continuous drain current of 3.5 A. The device has a maximum on-resistance of 100 mOhm at 3.5 A and 10 V gate drive, and a maximum gate threshold voltage of 3 V at 250 µA. It includes a logic-level gate feature for direct drive from low-voltage logic. The input capacitance is 420 pF at 30 V Vds, and the total gate charge is 13 nC at 5 V. Power dissipation is rated at 1 W. The operating junction temperature range is -55°C to 175°C. This part is designed for surface-mount assembly in the standard 8-SOIC (0.154", 3.90mm width) package, suitable for automated PCB processes. Typical applications include load switching, power management, and DC-DC converter designs where two independent MOSFET channels are needed in a compact footprint.
