AO8814#A

Overview

The AO8814#A is a dual N-channel enhancement mode MOSFET array manufactured by Alpha & Omega Semiconductor Inc. It features a common-drain configuration housed in an 8-TSSOP surface-mount package. The device supports a drain-source voltage (Vdss) of 20V and a continuous drain current (Id) of 7.5A at 25°C. Key electrical parameters include a maximum on-resistance (Rds(on)) of 16mΩ at Vgs=10V, a gate charge (Qg) of 14nC at Vgs=4.5V, and an input capacitance (Ciss) of 1295pF at Vds=10V. It operates within a junction temperature range of -55°C to 150°C with a maximum power dissipation of 1.5W.

Feature Summary

Utilizes advanced trench technology for low on-resistance and fast switching performance.
Optimized for logic-level gate drive operation with low threshold voltage requirements.
Dual N-channel common-drain configuration allows for efficient space-saving integration.

Applications

DC-DC converter synchronous rectification
Power management integrated circuit (PMIC) output stages
Battery protection circuits

Procurement Notes

Verify the specific suffix #A against the manufacturer's official documentation to confirm exact pinout compatibility and RoHS compliance status. Confirm that the 8-TSSOP package dimensions match the target PCB footprint. Ensure that the sourcing channel provides valid traceability records for this discontinued or legacy component series.

Selection Notes

Select this component when a compact dual N-channel solution is required for low-voltage applications. The 20V rating and 7.5A current capacity suit portable electronics. Compare Rds(on) and Qg values against alternatives to ensure efficiency targets are met. Verify thermal dissipation capabilities within the 1.5W limit for the intended enclosure environment.

Part Context

This part belongs to the AO881 family of dual MOSFET arrays from Alpha & Omega Semiconductor. It shares architectural similarities with the AO8810 and AO8812 but differs in specific current ratings and package variants. The AO8814 specifically targets high-density power applications requiring two matched N-channel transistors in a single small outline package.
