AOD472A

Overview

The AOD472A is a 30V N-Channel AlphaMOS power transistor utilizing latest trench technology. It features a maximum continuous drain current of 46A at TC=25°C and a pulsed drain current of 170A. The device offers a static drain-source on-resistance of less than 5mΩ at VGS=10V and less than 10mΩ at VGS=4.5V. Key electrical parameters include a gate threshold voltage ranging from 1.6V to 2.4V, total gate charge of 18.3nC to 33nC at VDS=15V, and forward transconductance of 83S. Thermal characteristics specify a junction-to-case resistance of 2.5°C/W typical.

Feature Summary

Latest Trench Power MOSFET technology for high performance
Very low RDS(on) at 4.5V gate-source voltage
High current capability with 100% UIS testing
RoHS and Halogen-Free compliant construction

Applications

DC/DC Converters in Computing
Isolated DC/DC Converters in Telecom
Isolated DC/DC Converters in Industrial applications

Procurement Notes

Verify the specific package variant (TO-251A/IPAK, TO-252/DPAK, or others) required for your design, as the datasheet covers multiple physical packages under the same part number. Confirm that the component meets consumer market qualification standards, as it is not authorized for life support devices. Ensure thermal management aligns with the specified junction-to-case and junction-to-ambient resistance values for your operating environment.

Selection Notes

Select this component when a 30V N-Channel MOSFET with high current handling up to 46A is required. The low on-resistance at both 10V and 4.5V gate drive voltages makes it suitable for logic-level control applications. Consider the thermal constraints and available package options (TO-251A, TO-252) based on your board layout and heat dissipation needs.

Part Context

The AOD472A belongs to the AlphaMOS series from Alpha & Omega Semiconductor Inc., designed for general-purpose power switching. It utilizes advanced trench technology to achieve low on-resistance and fast switching speeds. The product is qualified for the consumer market and is RoHS compliant.
