AO3407A

Overview

The AO3407A is a P-Channel MOSFET manufactured by Alpha & Omega Semiconductor Inc. It features a drain-source voltage (VDS) of -30V and a continuous drain current (ID) of -4.3A at VGS=-10V. The device utilizes advanced trench technology to achieve an on-state resistance (RDS(ON)) of less than 48mΩ at VGS=-10V and less than 78mΩ at VGS=-4.5V. It operates within a junction and storage temperature range of -55°C to 150°C, with a maximum power dissipation of 1.4W at 25°C ambient temperature.

Feature Summary

Advanced trench technology provides excellent on-state resistance and low gate charge for efficient switching performance.
Capable of operation as a load switch or in pulse-width modulation (PWM) applications due to fast switching characteristics.

Applications

Load switching
Pulse-width modulation (PWM) applications

Procurement Notes

Verify the specific datasheet revision and ordering suffixes directly with the manufacturer or authorized distributors before procurement. Confirm that the component meets RoHS compliance requirements and check for any recent product change notices (PCN) regarding manufacturing site or material composition updates to ensure compatibility with existing supply chains.

Selection Notes

Select this component for circuits requiring a compact P-Channel MOSFET with a 30V rating. Ensure the driving circuit can provide sufficient gate-source voltage to minimize RDS(ON), particularly if operating near the -4.5V threshold. Evaluate thermal management needs based on the specified junction-to-ambient thermal resistance and expected duty cycles.

Part Context

This part belongs to the AO34 series of small-signal MOSFETs produced by Alpha & Omega Semiconductor. It is housed in a SOT-23 surface-mount package, designed for space-constrained PCB layouts. The device is intended for general-purpose switching applications where low on-resistance and fast switching speeds are required.

Replacement Considerations

Check for direct pin-compatible alternatives from other manufacturers offering similar VDS and ID ratings. Verify that substitute components match the RDS(ON) specifications at the intended drive voltages (-10V and -4.5V) and confirm equivalent thermal characteristics for reliable operation.
