AOC2421

Overview

The AOC2421 is an 8V P-Channel MOSFET utilizing advanced trench technology. It features a drain-source voltage of -8V and a continuous source current of -0.6A at 25°C ambient temperature. The device offers low on-resistance, specified as less than 60mΩ at VGS=-2.5V and ID=-1.5A. It supports operation with gate voltages as low as 1.2V while maintaining a maximum VGS rating of ±5V. The component is housed in an AlphaDFN 0.97x0.97mm package.

Feature Summary

Advanced trench technology for excellent RDS(ON) performance
Low gate charge characteristics for efficient switching
Compatible with low gate drive voltages down to 1.2V

Applications

Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure compatibility with design requirements. Confirm that the AlphaDFN 0.97x0.97mm package dimensions align with PCB layout constraints. Review the absolute maximum ratings and thermal characteristics to ensure safe operating conditions are met within the intended application environment.

Selection Notes

Select this component for applications requiring low-voltage power management with compact footprint constraints. The low gate threshold voltage allows for direct interfacing with logic-level drivers. Ensure the thermal resistance and power dissipation limits are adequate for the expected load currents and ambient temperatures.

Part Context

This component belongs to the Alpha & Omega Semiconductor P-Channel MOSFET family. It is designed for surface-mount applications where space efficiency and low on-resistance are critical. The device is suitable for portable electronics and battery-powered systems requiring efficient power switching.

Replacement Considerations

Check datasheets for alternative parts offering similar voltage ratings and package sizes. Verify that substitute components meet the required RDS(ON) specifications and thermal performance criteria.
