AOD482

Overview

The AOD482 is a 100V N-Channel MOSFET utilizing advanced trench technology for low on-resistance. It features a drain-source voltage of 100V and a continuous drain current of 32A at VGS=10V. The device offers an RDS(ON) of less than 37mΩ at VGS=10V and less than 42mΩ at VGS=4.5V. It includes 100% UIS and Rg testing, with a junction temperature range of -55°C to 175°C.

Feature Summary

Advanced trench MOSFET technology providing extremely low RDS(ON).
Suitable for boost converters and synchronous rectifiers.
100% Unclamped Inductive Switching (UIS) tested.

Applications

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

Procurement Notes

Verify the specific package variant required, as the datasheet covers TO-251A (IPAK), TO-252 (DPAK), and potentially others. Confirm thermal performance requirements against the provided junction-to-ambient and junction-to-case resistance values. Ensure the application does not involve life support systems, as such usage is explicitly unauthorized by the manufacturer.

Selection Notes

Select this component for high-efficiency power conversion applications requiring robust avalanche capability. The low gate charge and fast switching times make it suitable for high-frequency designs. Consider the thermal derating curves when designing for high ambient temperatures or limited board space.

Part Context

The AOD482 belongs to Alpha & Omega Semiconductor's lineup of N-Channel enhancement mode field effect transistors. It is designed to replace older technologies in power management circuits, offering improved efficiency through reduced conduction losses and optimized switching characteristics for modern power supply architectures.

Replacement Considerations

Check pinout compatibility if substituting in existing designs. Verify that the replacement device meets or exceeds the 100V breakdown voltage and 32A current rating. Ensure the new component supports the required operating temperature range up to 175°C.
