AOD458

Overview

The AOD458 is a 250V N-Channel Enhancement Mode Field Effect Transistor fabricated using an advanced high voltage MOSFET process. It features a TO-252 (DPAK) surface-mount package with a maximum continuous drain current of 14A at VGS=10V and a typical on-resistance of 0.22Ω at VGS=10V, ID=7A. The device includes guaranteed avalanche capability and has undergone 100% UIS and Rg testing. Thermal characteristics include a junction-to-case resistance of 1°C/W and a junction-to-ambient resistance of 55°C/W in still air.

Procurement Notes

Verify the specific datasheet revision and ordering suffixes directly with Alpha & Omega Semiconductor or authorized distributors. Confirm that the component meets RoHS compliance requirements and check for any recent product change notices (PCN) regarding manufacturing updates or lifecycle status changes before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a 250V rating with moderate current handling capabilities in a compact DPAK package. Ensure the thermal design accounts for the specified junction-to-ambient resistance when operating without additional heatsinking. Verify that the gate drive voltage supports the specified on-resistance thresholds for optimal efficiency.

Part Context

The AOD458 belongs to Alpha & Omega Semiconductor's portfolio of N-Channel MOSFETs optimized for offline power supply designs. It utilizes trench technology to achieve low conduction losses and fast switching speeds. The device is intended for general-purpose power management in consumer, telecom, and industrial equipment where space constraints and thermal performance are critical.

Replacement Considerations

Check for electrically equivalent parts such as the AON6458 from the same manufacturer. When substituting, verify that the replacement part matches the voltage, current, and package specifications to ensure compatibility with existing board layouts and thermal management systems.
