AO3423 Description

Short technical summary and product information.

The AOS AO3423 is a 20V P-Channel MOSFET utilizing advanced trench technology. It provides excellent on-state resistance (RDS(ON)) and low gate charge, enabling operation with gate voltages as low as 2.5V. This device is suitable for load switch applications.

Key electrical characteristics include a Drain-Source Breakdown Voltage (BVDSS) of -20V and a continuous drain current (ID) of -2A at 25°C. The static drain-source on-resistance is as low as 92mΩ at VGS=-10V and 166mΩ at VGS=-2.5V. Dynamic parameters such as input capacitance (Ciss) are typically 325pF, and total gate charge (Qg) is 4.5nC.

The AO3423 is housed in a compact SOT23 package, making it ideal for space-constrained designs. It is designed for surface mount applications. The device operates within a junction and storage temperature range of -55°C to 150°C.

This MOSFET is qualified for industrial applications and includes typical ESD protection. It is well-suited for use in computing, consumer electronics, and motor drive applications.
