AOCA32116E

Overview

The AOCA32116E is a dual N-channel common-drain MOSFET array manufactured by Alpha & Omega Semiconductor Inc. It features a 20V drain-source voltage rating and supports a continuous drain current of 6A at ambient temperature. The device delivers a maximum on-resistance of 20 milliohms at 4.5V gate drive. Packaged in a compact 4-AlphaDFN (1.2x1.2mm) surface-mount format, it offers a thermal dissipation capacity of 1.7W. The component operates within a junction temperature range of -55°C to 150°C and complies with RoHS3 standards.

Feature Summary

• Dual N-channel configuration with common-drain topology for efficient load switching
• Ultra-compact 4-AlphaDFN package optimized for space-constrained designs
• Low on-resistance characteristics suitable for high-efficiency power paths

Applications

• Compact power-path management circuits
• Load-switching applications in portable electronics
• Battery protection systems requiring small form factors

Procurement Notes

Verify the specific ordering suffix and tape-and-reel quantity requirements against the manufacturer's official datasheet before procurement. Confirm that the selected variant matches the required 4-AlphaDFN package dimensions and thermal specifications. Ensure compliance with RoHS3 directives and check for any recent product change notices or lifecycle status updates from Alpha & Omega Semiconductor to guarantee long-term supply availability.

Selection Notes

Select this component when design constraints demand a minimal footprint alongside robust dual-channel switching capabilities. The 20V rating and 6A current handling make it appropriate for low-voltage DC bus applications. Evaluate the thermal performance within the 1.2x1.2mm package relative to the expected power dissipation. Consider the common-drain architecture for ground-referenced load control scenarios where space efficiency is critical.
