AO4892

Overview

The AO4892 is a dual N-channel MOSFET utilizing trench technology for high-frequency switching. It features a drain-source voltage of 100V and a continuous drain current of 4A at VGS=10V. The on-resistance is less than 68mΩ at VGS=10V and less than 94mΩ at VGS=4.5V. The device operates within a junction temperature range of -55°C to 150°C, with a maximum power dissipation of 2.0W. It includes 100% UIS and Rg testing.

Feature Summary

Optimized trench MOSFET technology minimizes conduction and switching losses through low RDS(ON), Ciss, and Coss values.
Validated for reliability with 100% Unclamped Inductive Switching (UIS) and gate resistance testing.

Applications

Boost converters
Synchronous rectifiers
Consumer power supplies
Telecom power supplies
Industrial power supplies
LED backlighting

Procurement Notes

Verify the specific package type and marking code against the manufacturer's latest datasheet revision before ordering. Confirm thermal performance requirements align with the specified junction-to-ambient resistance values under actual board layout conditions. Ensure compliance with RoHS directives if required by the end application.

Selection Notes

Select this component for applications requiring efficient high-frequency switching in dual-channel configurations. Consider the 100V rating and 4A continuous current capability when designing boost converters or synchronous rectification circuits. Evaluate thermal management needs based on the 2.0W power dissipation limit and SOIC-8 package constraints.

Part Context

The AO4892 belongs to Alpha & Omega Semiconductor's lineup of dual N-channel MOSFETs designed for power management applications. It shares the SOIC-8 footprint common to many surface-mount power devices but offers specific electrical characteristics optimized for efficiency in consumer and industrial power supply designs.

Replacement Considerations

Direct replacements include FDC3601N, FDS3601, FDS3912, KDS3601, KDS3912, AO4886, and AON6850. Verify pinout compatibility and electrical parameters such as VDS, ID, and RDS(ON) before substitution.
