AOD474B

Overview

The AOD474B is a 75V N-Channel MOSFET utilizing advanced trench technology. It features an extremely low on-resistance of less than 132mΩ at VGS=10V and less than 155mΩ at VGS=4.5V. The device supports a continuous drain current of 10A and a pulsed drain current of 60A. It includes 100% UIS and Rg testing for reliability. The component operates within a junction temperature range of -55°C to 175°C and is housed in a TO-252 (DPAK) package.

Feature Summary

Combines advanced trench MOSFET technology with a low resistance package to provide extremely low RDS(ON).
Includes 100% Unclamped Inductive Switching (UIS) and Gate Resistance (Rg) testing.
Designed for high-efficiency power switching applications.

Applications

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

Procurement Notes

Verify the specific datasheet revision, as Alpha & Omega Semiconductor reserves the right to improve product design, functions, and reliability without notice. Confirm that the application does not involve life support devices or systems, as such uses are explicitly unauthorized by the manufacturer. Ensure thermal management aligns with the specified junction-to-case and junction-to-ambient resistance values provided in the official documentation.

Selection Notes

Select this component for designs requiring a 75V N-Channel MOSFET with low conduction losses. Consider the 10A continuous current rating and the TO-252 package constraints. Evaluate the gate charge characteristics for switching speed requirements. Ensure the PCB layout supports the thermal dissipation limits defined by the junction-to-ambient resistance in still air environments.

Part Context

The AOD474B belongs to the Alpha & Omega Semiconductor AOD series of N-Channel MOSFETs. This series utilizes trench technology to achieve low on-resistance in surface-mount packages. The AOD474B specifically targets applications needing efficient power conversion in consumer, telecom, and industrial sectors.

Replacement Considerations

Check for direct substitutes with identical 75V ratings, similar RDS(ON) specifications, and compatible TO-252 pinouts. Verify that any replacement maintains the required 10A continuous current capability and thermal performance characteristics.
