Overview
The UMW AO3403A is a P-Channel MOSFET housed in an SOT-23 package. It features a drain-source voltage rating of -30V and a continuous drain current of -2.6A at VGS=-10V. The device exhibits a maximum on-resistance of 75mΩ at VGS=-10V and 85mΩ at VGS=-4.5V. Thermal characteristics include a power dissipation of 1.4W at 25°C, with junction-to-ambient thermal resistance values of 90°C/W and 125°C/W under specific mounting conditions.
Feature Summary
- P-Channel MOSFET architecture designed for surface-mount applications
- Low on-state resistance to minimize conduction losses
- Integrated body diode with defined reverse recovery characteristics
- Operational within a wide temperature range from -55°C to 150°C
Applications

Procurement Notes
Verify the component marking code '17A3NL' against the official datasheet to confirm authenticity. Ensure the ordering information specifies the tape and reel delivery mode with a base quantity of 3000 units. Confirm that the SOT-23 package dimensions align with your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when a compact P-Channel solution is required for 30V systems. Evaluate the gate threshold voltage range (-0.6V to -1.4V) to ensure compatibility with your logic levels. Consider the thermal resistance parameters if operating near the maximum junction temperature limit of 150°C.
Part Context
This part belongs to the UMW discrete semiconductor portfolio, specifically within their MOSFET lineup. It serves as a standard switching element for general-purpose electronic designs. The manufacturer provides detailed electrical curves and safe operating area data to support circuit simulation and reliability analysis.
Replacement Considerations
Cross-reference pinout configurations and absolute maximum ratings when substituting. Verify that alternative components meet the same -30V and -2.6A specifications. Ensure the replacement package matches the SOT-23 form factor for direct board integration.
