00 — Overview

What the HL3401A family does

The HL3401A is a P-channel MOSFET in the SOT-23 package, designed for battery protection, load switching, and power management. It features a -30 V drain-source voltage rating, -4.2 A continuous drain current, and on-resistance below 65 mΩ at -10 V gate drive. The device supports junction temperatures from -55 to +150 °C and includes a body diode rated for -1.0 A. Its low input capacitance and fast switching times make it suitable for high-speed applications requiring efficient power control in commercial and industrial systems.
