AO3401AL

Overview

The AO3401AL is a P-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to deliver excellent RDS(ON) and low gate charge, supporting operation with gate voltages as low as 2.5V. The device features a Drain-Source Voltage (VDS) of -30V and a Continuous Drain Current (ID) of -4.3A at VGS = -10V. Electrical characteristics include an on-resistance of less than 46mΩ at VGS = -10V, less than 55mΩ at VGS = -4.5V, and less than 80mΩ at VGS = -2.5V. It is housed in a TO-236 (SOT-23) package.

Feature Summary

Advanced trench technology provides excellent on-resistance and low gate charge for efficient switching.
Capable of operating with gate voltages as low as 2.5V, facilitating direct interface with low-voltage logic.
Designed specifically for use as a load switch or in general applications requiring compact surface-mount solutions.

Applications

Load switching
General purpose electronic applications

Procurement Notes

Verify the specific ordering suffix 'L' against the manufacturer's current documentation to confirm Halogen-Free status and RoHS compliance. Ensure the component is sourced from authorized distributors to guarantee authenticity. Confirm that the intended application aligns with the consumer market qualification stated in the datasheet.

Selection Notes

Select this component for circuits requiring a compact P-channel MOSFET with low gate drive requirements. The device is suitable for applications where space is constrained due to its SOT-23 packaging. Consider the thermal resistance ratings when designing for continuous current loads to ensure junction temperatures remain within safe operating limits.

Part Context

The AO3401AL is electrically identical to the AO3401A model. Both variants share the same pinout, electrical specifications, and functional capabilities. The primary distinction lies in the manufacturing attributes associated with the 'L' suffix, which denotes specific environmental compliance standards such as being Halogen-Free.

Replacement Considerations

The AO3401A is confirmed as an electrically identical substitute. Other generic P-channel MOSFETs in the SOT-23 package may serve as replacements if their voltage, current, and on-resistance parameters meet or exceed those specified for the AO3401AL.
