Product Description

The AOS AO3403 is a 30V P-Channel MOSFET housed in a compact SOT-23 package, designed for efficient power management in space-constrained applications. It features a continuous drain current of -4.3A (at VGS = -10V) and a low on-resistance (RDS(on)) of 38mΩ (max) at VGS = -10V, enabling high-efficiency switching with minimal power loss. Operating within a voltage range of -30V (VDS) and a temperature range of -55°C to +150°C, this MOSFET is ideal for battery protection circuits, load switching, DC-DC converters, and motor control systems in consumer electronics, portable devices, and industrial equipment. Its compact SOT-23 package simplifies PCB layout, while its robust performance ensures reliable operation. Key advantages include low gate charge, fast switching speeds, and thermal stability, though its current and voltage ratings may limit use in high-power applications. It does not include communication interfaces or sensors and operates as a standalone power switch.
