Product Overview
The AO3401A is a P-channel MOSFET designed for low-voltage power management, high-side load switching, and compact battery-powered applications. It features a 30V drain-source voltage rating, 4A continuous drain current, and a maximum drain-source on-resistance of 44mΩ at a -10V gate drive. Its low gate charge and support for low-voltage gate drive make it suitable for efficient switching in logic-controlled power circuits.
Packaged in a compact SOT-23 surface-mount package, the AO3401A is well suited to portable electronics, battery switching, DC power distribution, and other space-constrained power-control designs.
