AO7403 Description

Short technical summary and product information.

The AO7403 from Alpha & Omega Semiconductor is a P-Channel Enhancement Mode Field Effect Transistor. It utilizes advanced trench technology to achieve excellent RDS(ON) and low gate charge, operating with gate voltages as low as 1.8V. This MOSFET is housed in a compact SOT-323 (SC-70) surface-mount package.

 

Key electrical characteristics include a Drain-Source Voltage (VDS) of -20V and a Continuous Drain Current (ID) of -0.7A at 25°C (VGS = -4.5V). The Static Drain-Source On-Resistance (RDS(ON)) is specified as less than 470mΩ at VGS = -4.5V. The device also features a typical Gate Threshold Voltage (VGS(th)) of -0.6V.

 

With its robust performance and small footprint, the AO7403 is suitable for a wide range of applications, including load switching, low current inverters, and low current DC-DC converters. It is ESD protected to 2KV HBM. The AO7403 is Pb-free and meets ROHS & Sony 259 specifications.
