AON3814L

Overview

The AON3814L is a dual N-channel enhancement mode field effect transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to deliver low on-resistance and gate charge, supporting operation with gate voltages as low as 1.8V while maintaining a 12V maximum VGS rating. The device features a common-drain configuration suitable for uni-directional or bi-directional load switching applications. Key electrical parameters include a drain-source voltage (VDS) of 20V, a continuous current (ID) of 6A at VGS = 4.5V, and an on-resistance (RDS(ON)) of less than 17mΩ at VGS = 4.5V. The component includes ESD protection.

Feature Summary

• Advanced trench technology provides excellent RDS(ON) and low gate charge characteristics.
• Common-drain configuration facilitates use as a uni-directional or bi-directional load switch.
• Operates with gate voltages as low as 1.8V while retaining a 12V VGS(MAX) rating.
• Integrated ESD protection enhances device reliability.

Applications

• Uni-directional load switching
• Bi-directional load switching

Procurement Notes

Verify the specific suffix 'L' against official Alpha & Omega Semiconductor datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with 1.8V logic levels if used in low-voltage control circuits. Confirm RoHS compliance status through manufacturer documentation prior to procurement.

Selection Notes

Select this component for applications requiring dual N-channel MOSFETs in a compact form factor with low gate drive requirements. The 20V rating and 6A current capacity suit low-voltage power management tasks. Evaluate thermal performance based on the specific PCB layout and ambient conditions, as the datasheet specifies RDS(ON) values at various VGS levels.

Part Context

The AON3814L belongs to Alpha & Omega Semiconductor's portfolio of discrete power devices designed for high-volume consumer and industrial electronics.
