Overview
The AO3401L is a P-channel enhancement mode field effect transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to deliver low on-resistance and gate charge, enabling operation with gate voltages as low as 2.5V. The device features a drain-source voltage of -30V and a continuous drain current of -4A. Key electrical parameters include an on-resistance of less than 65mΩ at VGS=-4.5V and less than 120mΩ at VGS=-2.5V. It is housed in a surface-mount SOT-23 package.
Feature Summary
- Advanced trench technology for excellent on-resistance and low gate charge
- Capable of operation with gate voltages as low as 2.5V
- Suitable for use as a load switch or in PWM applications
Applications
- Load switching circuits
- Pulse Width Modulation (PWM) applications
Procurement Notes
Verify the specific suffix 'L' indicates Green Product compliance per Sony 259 specifications while confirming electrical identity with the standard AO3401 variant. Ensure sourcing channels provide official datasheets to validate RoHS status and confirm the component remains active in production before finalizing procurement plans.
Selection Notes
Select this component for designs requiring efficient power management with low drive voltage requirements. The SOT-23 package suits space-constrained layouts. Verify that the system's gate drive voltage aligns with the specified thresholds to ensure optimal on-resistance performance during operation.
Part Context
This part belongs to the AO34xx series of N-channel and P-channel MOSFETs produced by Alpha & Omega Semiconductor. The AO3401L is electrically identical to the standard AO3401 model but offers a Green Product ordering option. Both variants are Pb-free and meet ROHS standards.
Replacement Considerations
The standard AO3401 is electrically identical and serves as a direct functional substitute. Other P-channel MOSFETs within the same voltage and current ratings may be considered if pin compatibility and thermal characteristics match.
