AO4801L

Overview

The AO4801A is a dual P-channel MOSFET array housed in an 8-SOIC package. It features a drain-source voltage (VDS) of -30V and a continuous drain current (ID) of -5A at VGS=-10V. The on-state resistance (RDS(ON)) is less than 48mΩ at VGS=-10V, 57mΩ at VGS=-4.5V, and 80mΩ at VGS=-2.5V. Key dynamic parameters include a total gate charge (Qg) of 9nC at VGS=4.5V, input capacitance (Ciss) of 780pF, and turn-off delay time (tD(off)) of 41ns. The device supports a maximum junction temperature of 150°C and has been tested for 100% UIS and Rg.

Feature Summary

• Dual P-channel configuration providing two independent channels within a single compact surface-mount package.
• Advanced trench MOSFET technology engineered to deliver extremely low on-state resistance for improved efficiency.
• Logic-level gate compatibility allowing effective switching performance with lower gate drive voltages such as -4.5V and -2.5V.
• Robust construction validated through 100% Unclamped Inductive Switching (UIS) testing for demanding load applications.

Applications

• Load switching circuits requiring efficient power management.
• Pulse Width Modulation (PWM) control applications.
• Low-side or high-side power switching in consumer electronics.

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm exact electrical tolerances and packaging variations. Confirm component availability status directly with Alpha & Omega Semiconductor Inc., as distribution listings may not reflect current production cycles. Ensure the procurement channel provides valid traceability documents consistent with the manufacturer's quality standards.

Selection Notes

Select this component when a dual P-channel solution is required in an SOIC-8 footprint. Evaluate the RDS(ON) specifications at your specific operating gate voltage (-10V, -4.5V, or -2.5V) to ensure thermal constraints are met. Consider the 150°C maximum junction temperature rating for high-temperature environments and verify that the 5A continuous current rating aligns with your circuit's peak load requirements.

Part Context

The AO4801A belongs to the AO4801 series from Alpha & Omega Semiconductor Inc., designed for general-purpose switching in consumer markets. It utilizes TrenchMOS technology to minimize conduction losses. The datasheet indicates it is qualified for consumer applications and explicitly excludes use in life support devices without authorization.

Replacement Considerations

Direct cross-references require matching the -30V P-channel specification, dual channel configuration, and SOIC-8 package. Verify pinout compatibility and thermal characteristics before substitution. Consult official replacement guides from Alpha & Omega Semiconductor Inc. for validated alternatives.
