AO4701

Overview

The AO4701 is a P-Channel Enhancement Mode MOSFET with an integrated Schottky diode, manufactured by Alpha & Omega Semiconductor Inc. It utilizes advanced trench technology to achieve low on-resistance and gate charge. The device features a drain-source voltage of -30V and a continuous drain current of -5A at 25°C. On-resistance is specified as less than 48mΩ at VGS=-10V, 57mΩ at VGS=-4.5V, and 80mΩ at VGS=-2.5V. The integrated Schottky diode supports a forward current of 3A with a forward voltage of 0.5V at 1A. It is housed in an 8-SOIC package.

Feature Summary

Integrates a Schottky diode to facilitate bidirectional blocking switch implementation
Utilizes advanced trench technology for excellent on-resistance and low gate charge
Rated for 100% Unclamped Inductive Switching (UIS) testing
Rated for 100% Gate Charge testing

Applications

Bidirectional blocking switches
Load switching applications
General purpose power management circuits

Procurement Notes

Verify the specific revision status of the datasheet, as the product documentation indicates a May 2011 revision date. Confirm that the component meets consumer market qualification standards, as AOS explicitly states that life support devices or systems are not authorized uses. Ensure the selected supplier provides traceability for the SOIC-8 package and verifies the electrical parameters against the provided absolute maximum ratings table.

Selection Notes

Select this component when a compact solution for bidirectional blocking is required within a 30V system. The integrated Schottky diode eliminates the need for external components, reducing board space. Consider the thermal resistance characteristics, specifically the junction-to-ambient rating of 90°C/W on a standard FR-4 board, to ensure adequate heat dissipation for the intended duty cycle and ambient temperature conditions.

Part Context

The AO4701 belongs to the AO47 series of power MOSFETs from Alpha & Omega Semiconductor. This series focuses on providing high-performance solutions for consumer electronics and general-purpose applications through the use of trench technology. The integration of the Schottky diode distinguishes it from standard single FET packages, offering a specialized function for specific circuit topologies requiring reverse current handling.
