AO3401A P Channel MOSFET SOT-23 30V 4A Low RDS(ON)

The AO3401A is a high-performance P-Channel Enhancement Mode MOSFET manufactured using advanced trench technology to deliver low on-resistance and efficient switching performance. Packaged in a compact SOT-23 surface-mount package, it is widely used for battery-powered and low-voltage electronic applications.

With a −30V drain-source voltage (VDS) rating and −4A continuous drain current, the AO3401A provides excellent efficiency for high-side load switching, reverse polarity protection, battery management systems, and portable electronics. Its low gate threshold voltage allows direct operation from 2.5V, 3.3V, and 5V logic without requiring a dedicated gate driver. Ultra-low RDS(ON) minimizes power loss and heat generation.
