Package

The FDS4685 is typically offered in a SO-8 (Small Outline) package type. This surface-mount package is designed for compact applications, providing efficient space utilization on PCBs.

Pinout

The FDS4685 is a dual N-channel MOSFET in a compact 8-pin package (SO-8). It features a pin count of 8, with the following functions:
1. Gate (G): Controls the MOSFET's on/off state.
2. Drain (D): Connects to the load; current flows out of this pin when the MOSFET is on.
3. Source (S): Connects to ground or the negative side of the load; current flows into this pin when the MOSFET is on.
4. Common Pins: Typically, the device has two sets of G, D, and S pins for its dual MOSFET configuration.
These components are commonly used in power management applications, including load switching and DC-DC converters, due to their low on-resistance and fast switching capabilities.
