Description
AO4482 is a power MOSFET from Alpha & Omega Semiconductor. It’s an N-channel enhancement‑mode transistor used as the switching element in power electronics. Typical applications include switch‑mode power supplies, DC‑DC converters, motor drivers, and synchronous rectification. The device combines low on‑resistance, fast switching, and robust SOA to enable high efficiency in moderate‑ to high‑current designs. Because AO4482 may refer to different variants, always check the datasheet for the exact VDS, ID, and RDS(on) rating, as well as packaging, thermal resistance, and avalanche energy limits.
Key considerations when using AO4482:
- Drain‑to‑source voltage (VDS) and continuous drain current (ID)
- On‑resistance (RDS(on)) at your gate drive voltage
- Gate charge (Qg) and drive impedance
- Package type and thermal performance
- Safe operating area and avalanche rating
Typical pinouts depend on package; refer to the specific datasheet for wiring. In short: AO4482 = a high‑performance power MOSFET used as a switch; confirm variant specs.
