Features

The FDD4685 is a P-channel MOSFET with the following key features:
- Voltage Rating: -30V (drain-to-source)
- Current Rating: -12A (continuous drain current)
- Low On-Resistance (RDS(on)): 18mΩ (max at VGS = -10V)
- Gate Threshold Voltage (VGS(th)): -1V to -2V (typical)
- Power Dissipation: 2.5W (max)
- Fast Switching Speed: Suitable for high-efficiency applications
- Package: TO-252 (DPAK), surface-mountable
- Applications: Power management, load switching, DC-DC converters, and battery protection circuits.
Its low RDS(on) and compact package make it ideal for space-constrained, high-efficiency designs.
