The AO4801HL is a dual-channel P-channel MOSFET array manufactured by Alpha & Omega Semiconductor Inc. It features a drain-source voltage (Vdss) rating of 30V and a continuous drain current (Id) of 5A at 25°C. The device utilizes an 8-pin SOIC package for surface mount installation. Key electrical characteristics include a gate-source voltage (Vgs) maximum of ±20V and a power dissipation capability defined by thermal constraints. This component is designed for applications requiring compact dual-channel switching solutions within low-voltage DC-DC converter and load switch circuits.
Verify the specific ordering suffix and manufacturing date code against the latest Alpha & Omega Semiconductor datasheet to ensure compliance with current RoHS3 standards. Confirm that the 8-pin SOIC package dimensions match your PCB layout requirements prior to final procurement approval.
Select this component when a dual P-channel solution is required in a small form factor. Ensure the 30V rating exceeds the maximum circuit voltage and the 5A current limit accommodates peak load demands without exceeding thermal dissipation limits for the chosen operating environment.
This part belongs to the AO4801 series, which includes variants such as AO4801AS and AO4801L. These devices are commonly used in consumer electronics and industrial control systems where space-constrained dual-switching functionality is necessary for power management tasks.
Direct substitutes may include AO4801AS or AO4801L, provided the package type and electrical ratings are compatible. Verify pinout compatibility and thermal performance before substitution.
