AO4812L

Overview

The AO4812 is a dual N-channel enhancement mode MOSFET manufactured by Alpha & Omega Semiconductor Inc. utilizing advanced trench technology for low gate charge and excellent on-resistance. It features a drain-source voltage of 30V, continuous drain current of 6A at VGS=10V, and maximum junction temperature of 150°C. On-resistance is less than 30mΩ at VGS=10V and 42mΩ at VGS=4.5V. The device includes 100% UIS and Rg testing, with thermal resistance (junction-to-ambient) at 90°C/W in still air.

Feature Summary

Advanced trench technology provides low gate charge and excellent on-resistance.
Dual configuration enables compact synchronous rectifier combinations for buck converters.
100% Unclamped Inductive Switching (UIS) tested for reliability.

Applications

Buck converters
Synchronous rectifiers

Procurement Notes

Verify the specific package type and manufacturer lot codes against the official datasheet before procurement. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure storage conditions adhere to the specified moisture sensitivity level to prevent damage during soldering.

Selection Notes

Select this component when a dual N-channel MOSFET is required for low-voltage synchronous rectification. Evaluate the 30V rating and 6A current capacity against circuit load requirements. Consider the thermal performance and package constraints for the intended PCB layout.

Part Context

The AO4812 belongs to the Alpha & Omega Semiconductor dual MOSFET family designed for power management applications. It serves as an alternative to single-channel solutions where space efficiency is critical. The device integrates two independent N-channel FETs in a single package.

Replacement Considerations

Check pinout compatibility and electrical specifications such as VDS, ID, and RDS(ON) when substituting. Verify that any replacement part supports the same switching characteristics and thermal limits required by the original design.
