FDS4685 Description

Short technical summary and product information.

The FDS4685 is a P-Channel MOSFET manufactured by On Semiconductor. It features a maximum drain-to-source voltage (Vdss) of 40 V and a continuous drain current (Id) of 8.2 A at ambient temperature. The device has a low drain-source on-resistance of 27 mOhm at Id = 8.2 A with Vgs = 10 V. Drive voltage options are 4.5 V and 10 V for Rds(on) optimization.

 

The gate charge is 27 nC at Vgs = 5 V, and the input capacitance is 1872 pF at Vds = 20 V, providing reasonable switching performance for load-switching and power management applications. The maximum gate-source voltage is ±20 V, and the gate threshold voltage is 3 V at Id = 250 µA.

 

Power dissipation is rated at 2.5 W at ambient temperature, and the operating junction temperature range spans from -55°C to +150°C. The device is housed in an industry-standard 8-SOIC surface-mount package (0.154" width, 3.90 mm), making it suitable for compact PCB layouts.
