AOB290L

Overview

The AOB290L is a 100V N-Channel MOSFET utilizing Trench technology for high-frequency switching. It features a maximum drain-source voltage of 100V and continuous drain current ratings of 140A at 25°C case temperature and 110A at 70°C case temperature. The on-resistance (RDS(ON)) is less than 3.5mΩ at VGS=10V, with a gate threshold voltage ranging from 2.9V to 4.1V. Total gate charge is typically 90nC at 10V. The device operates within a junction temperature range of -55°C to 175°C.

Feature Summary

Optimized Trench MOSFET technology designed for efficient high-frequency switching performance.
Extremely low combination of RDS(ON) and Crss to minimize power losses.
Soft recovery body diode ensures controlled switching behavior.
100% tested for Unclamped Inductive Switching (UIS) capability.

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 TO-220 and TO-263 packages. Confirm that the component meets RoHS compliance standards if applicable to your manufacturing process. Ensure thermal management designs account for the specified junction-to-case and junction-to-ambient thermal resistances under actual operating conditions.

Selection Notes

Select this component when a 100V rating and high current handling are required for synchronous rectification or boost applications. Consider the TO-263 surface mount package for automated assembly or the TO-220 through-hole option depending on board layout constraints. Evaluate thermal dissipation requirements against the provided derating curves to ensure reliable operation within the 175°C maximum junction temperature limit.

Part Context

The AOB290L belongs to the AOT/AOB series of N-Channel MOSFETs manufactured by Alpha & Omega Semiconductor. These devices are engineered for general-purpose power switching applications requiring robust performance in consumer, telecom, and industrial environments. The product line emphasizes efficiency through optimized trench technology and low on-resistance characteristics.

Replacement Considerations

The datasheet explicitly pairs the AOB290L with the AOT290L, indicating they share identical electrical specifications and functionality. Verify pinout compatibility and package dimensions before substitution. No other substitute part numbers are documented in the provided source material.
