FPF2286UCX

FPF2286UCX is a power MOSFET from the FPF family (onsemi/Fairchild heritage). It’s an N-channel enhancement‑mode device intended for switching power electronics.
Key points:
- Used as a high-current switching element in DC‑DC converters, motor drivers, and power management stages.
- UCX denotes a specific surface‑mount package; check the datasheet for the exact pinout and thermal characteristics.
- Expect common MOSFET specs to verify: drain current rating, on-resistance (Rds(on)), gate threshold, switching speed, and thermal resistance.
How to use:
- Use as a low‑side switch (source to ground) or per your topology.
- Drive the gate with a suitable logic‑level voltage relative to the source.
- Include proper gate resistors, gate‑drive considerations, and adequate heat sinking to meet SOA and thermal limits.
Where to get details:
- Consult the official Onsemi/Fairchild datasheet for FPF2286UCX (pinout, Vds, Id, Rds(on), safe operating area, packaging).

Manufacturer: Fairchild Semiconductor (now part of ON Semiconductor). Fairchild was a global semiconductor company that designs and manufactures discrete devices and integrated circuits (e.g., transistors, diodes, power MOSFETs, ICs). In 2016 Fairchild was acquired by ON Semiconductor, a major multinational semiconductor maker.

FPF2286UCX is a dual MOSFET used in compact, high-efficiency power stages. Typical application areas include:
- Synchronous buck/boost regulator front-ends in portable devices (phones, tablets, laptops)
- USB-C PD power paths and other power-switch circuits
- Battery charging and power-path management
- Load-switching, hot-swap, and rail-OR’ing in power-management networks
- Automotive/industrial power-management circuits and motor drive setups (where low Rds(on) and good switching performance are needed)
Note: check the datasheet for exact rating and package details.

FPF2286UCX uses an 8‑pin X2SON (leadless) package, typically about 2.9 × 2.9 mm.
