AOI4286

Overview

The AOI4286 is a 100V N-Channel MOSFET utilizing trench technology optimized for high-frequency switching. It features a maximum drain-source voltage of 100V and a continuous drain current of 14A at 25°C case temperature. The device offers an on-resistance of less than 68mΩ at VGS=10V and less than 92mΩ at VGS=4.5V. It supports a junction temperature range from -55°C to 175°C and is available in the TO-251A (IPAK) package.

Feature Summary

Trench MOSFET technology minimizes conduction and switching power losses through low RDS(ON), Ciss, and Coss values.
Capable of handling repetitive avalanche energy with 100% UIS testing verification.

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 both AOD4286 (TO-252/DPAK) and AOI4286 (TO-251A/IPAK). Confirm thermal management requirements against the specified junction-to-case and junction-to-ambient resistance values. Ensure the application design complies with the absolute maximum ratings provided in the official documentation.

Selection Notes

Select this component for applications requiring efficient high-frequency switching performance. The low gate charge and fast switching times make it suitable for synchronous rectification. Evaluate the thermal derating curves to ensure the operating conditions remain within the safe operating area limits defined by the manufacturer.

Part Context

This part belongs to the Alpha & Omega Semiconductor lineup of N-Channel MOSFETs. It is designed to provide efficient power management solutions for various electronic systems. The device represents a balance between low on-resistance and robust switching capabilities, targeting modern power supply designs.

Replacement Considerations

Check for pin-compatible alternatives within the same voltage and current class if availability is an issue. Verify that any substitute matches the critical parameters such as RDS(ON), Qg, and package dimensions to ensure seamless integration into existing PCB layouts.
