AOB240L

Overview

The AOB240L is a surface-mount N-channel MOSFET utilizing Trench technology, optimized for high-frequency switching efficiency. It features a drain-source voltage of 40V and a continuous drain current of 85A at TC=25°C. The device achieves an extremely low on-resistance of less than 2.9mΩ at VGS=10V and less than 3.7mΩ at VGS=4.5V. Key electrical parameters include a gate threshold voltage of 1V to 2.2V, total gate charge of 49nC to 72nC at 10V, and input capacitance of 3510pF. Thermal characteristics specify a junction-to-case resistance of 0.85°C/W and a maximum junction temperature range of -55°C to 175°C.

Feature Summary

Trench MOSFET technology optimized for efficient high-frequency switching performance
Minimized power losses through an extremely low combination of RDS(ON) and Crss
100% UIS (Unclamped Inductive Switching) tested for reliability
100% Rg (Gate Resistance) tested

Applications

Procurement Notes

Verify the specific package type and ordering suffix against official Alpha & Omega Semiconductor documentation before procurement. Confirm that the component meets all applicable export control rules and legal requirements. Evaluate product suitability for intended applications as customer responsibility. Ensure compliance with manufacturer terms and conditions of sale.

Selection Notes

Select this component based on its 40V rating and 85A continuous current capability in TO-263 packages. Consider the low thermal resistance of 0.85°C/W for heat dissipation requirements. Verify compatibility with drive voltages of 4.5V or 10V given the specified on-resistance thresholds. Assess PCB design impact on junction-to-ambient thermal impedance.

Part Context

The AOB240L belongs to the AOT240L/AOB240L/AOTF240L family of 40V N-channel MOSFETs manufactured by Alpha & Omega Semiconductor.
