AO4290A

Overview

The AO4290A is a single N-channel MOSFET utilizing AlphaSGT trench technology, housed in an SOIC-8 surface-mount package. It features a drain-source voltage rating of 100V and a continuous drain current of 15.5A at VGS=10V. The device exhibits low on-resistance, specified as less than 6.4mΩ at VGS=10V and less than 7.6mΩ at VGS=4.5V. Key electrical parameters include a gate threshold voltage ranging from 1.3V to 2.3V, total gate charge of 65nC to 95nC at 10V, and input capacitance of 4525pF. Thermal characteristics define a maximum junction temperature of 150°C with a junction-to-ambient thermal resistance of 75°C/W.

Feature Summary

Employs AlphaSGT trench technology for optimized performance
Features logic-driven capability with low gate threshold voltage
Includes integrated body diode with fast reverse recovery characteristics
Verified through 100% Unclamped Inductive Switching (UIS) testing

Applications

Synchronous rectification for Quick Charger 3.0 systems
Synchronous rectification for AC/DC adapters
Synchronous rectification for DC/DC brick power supplies

Procurement Notes

Verify the specific orderable part number against the manufacturer's current catalog to ensure availability, as component status may change. Confirm that the required package type matches the SOIC-8 specification. Ensure compliance with RoHS and halogen-free requirements if mandated by the design. Evaluate suitability for intended applications, noting that critical life support uses are not authorized without explicit liability agreements.

Selection Notes

Select this component for designs requiring high-voltage handling up to 100V with efficient synchronous rectification. The low RDS(ON) values at both 10V and 4.5V drive levels make it suitable for logic-level control interfaces. Consider the thermal resistance and power dissipation limits when designing heat management solutions for the SOIC-8 package.

Part Context

This device belongs to the AlphaSGT product line from Alpha & Omega Semiconductor Inc., focusing on advanced trench MOSFET technologies. The SOIC-8 packaging provides a compact solution for surface-mount assembly. The component is designed to meet modern efficiency standards for power conversion applications.
