概述

Description

AOD2922 is a power MOSFET part number from Alpha & Omega Semiconductor (AOS). It designates a high-current, low-Rds(on) switching transistor used in power electronics such as DC-DC converters, synchronous buck/boost regulators, and motor drivers. The exact electrical ratings (voltage, current, on-resistance), package, gate threshold, and protection features vary by variant, so the precise specs come from the datasheet.
Key points to check in the datasheet:
- Vds (drain–source voltage) and Id (continuous current)
- Rds(on) at a given Vgs and the gate-charge characteristics
- Package type (e.g., DPAK, SO-8) and thermal considerations
- Gate threshold and any protection features (body diode, avalanche energy)
Common use:
- As a high- or low-side switch in power-management circuits and switching regulators
How to get specifics:
- Look up the AOS AOD2922 datasheet from the manufacturer or distributors, and verify the exact variant and footprint. Be aware of similarly marked parts from other vendors.

Package

Package type: D2PAK (TO-263) for the AOD2922 (power MOSFET). Always verify the exact variant in the datasheet.

Pinout

Pin count: 6 pins (typical in SOT-23-6 package; other packages may vary).
Function: Dual N-channel power MOSFET device (two N-channel MOSFETs in one package, for switching in DC-DC converter circuits). For exact pinout, consult the specific datasheet/package variant.
