AO4268

Overview

The AO4268 is a 60V N-Channel AlphaSGT™ MOSFET in an SOIC-8 package. It features a maximum continuous drain current of 19A at VGS=10V and <4.8mΩ RDS(ON) at VGS=10V, or <6.5mΩ at VGS=4.5V. The device has a gate threshold voltage range of 1.3V to 2.3V, total gate charge (Qg) of 65nC at 10V, and input capacitance (Ciss) of 2500pF. It supports a pulsed drain current of 14.5A, operates within -55°C to 150°C junction temperature, and includes 100% UIS testing.

Feature Summary

Utilizes Trench Power AlphaSGT technology for low on-resistance and gate charge
Includes 100% Unclamped Inductive Switching (UIS) testing
Features 100% Gate Resistance (Rg) testing

Applications

Synchronous rectification for AC-DC quick chargers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape & reel specifications. Ensure the component meets RoHS compliance standards required by your assembly process. Confirm that the supplier provides valid traceability records for the active product lifecycle status.

Selection Notes

Select this component for applications requiring high efficiency in synchronous rectification circuits. The low RDS(ON) values at both 10V and 4.5V gate voltages support effective performance across varying drive conditions. The 60V breakdown voltage and 19A current rating suit compact power supply designs.

Part Context

This part belongs to the AlphaSGT family from Alpha & Omega Semiconductor, designed for general-purpose switching applications. The SOIC-8 surface-mount package facilitates automated assembly. The device integrates body diode characteristics suitable for freewheeling operations in bridge configurations.

Replacement Considerations

Check datasheets for alternative 60V N-channel MOSFETs in SOIC-8 packages with comparable RDS(ON) and current ratings. Verify pinout compatibility and thermal resistance parameters before substitution.
