AO3415A

Overview

The AO3415A is a P-Channel MOSFET in an SOT-23 package. It features a Drain-Source Voltage (VDS) of -20V and a Continuous Drain Current (ID) of -5A at VGS = -4.5V. The On-Resistance (RDS(ON)) is less than 41mΩ at VGS = -4.5V, less than 53mΩ at VGS = -2.5V, and less than 65mΩ at VGS = -1.8V. Gate-Source Voltage (VGS) is rated at ±8V. Power Dissipation (PD) is 1.5W at 25°C. Junction Temperature Range is -55 to 150°C.

Feature Summary

Advanced trench technology provides excellent on-resistance and low gate charge.
Capable of operation with gate voltages as low as 1.8V.
Integrated ESD protection for enhanced reliability.

Applications

Load switch applications
Power management circuits
Battery protection systems

Procurement Notes

Verify the specific datasheet revision against your design requirements. Confirm that the thermal resistance values align with your PCB copper area and airflow conditions. Ensure the operating junction temperature remains within the specified -55°C to 150°C range during system integration.

Selection Notes

Select this component when space is constrained by the SOT-23 footprint and low-voltage logic driving is required. The device supports direct drive from 1.8V logic levels. Evaluate the thermal performance based on your specific board layout, as the junction-to-ambient resistance varies significantly with copper area.

Part Context

This part belongs to Alpha & Omega Semiconductor's lineup of surface-mount power transistors. It utilizes advanced trench technology to achieve high performance in a compact form factor. The device is designed for efficiency in low-voltage switching environments.

Replacement Considerations

Direct pin-compatible replacements include VB2290 and BL3415ES. Verify that substitute components meet the same -20V voltage rating and current handling capabilities before implementation.
