AOCA32112E

Overview

The AOCA32112E is a dual N-channel silicon MOSFET array manufactured by Alpha & Omega Semiconductor Inc. It features a maximum drain-source voltage (Vdss) of 20V and a continuous drain current (Id) of 4.5A at ambient temperature. The device is housed in a surface-mount 4-AlphaDFN package measuring 0.97x0.97 mm, with a maximum power dissipation of 1.1W at Ta. It complies with RoHS3 standards and has a moisture sensitivity level of 1.

Feature Summary

Dual N-channel configuration with common-drain architecture for integrated circuit applications
Compact 4-AlphaDFN surface-mount package designed for space-constrained designs
Green silicon technology optimized for efficiency and thermal performance

Applications

Portable battery-powered devices requiring low-voltage switching
DC-DC converter circuits for step-down or step-up topologies
Load switching and protection in mobile consumer electronics

Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant, as Alpha & Omega Semiconductor utilizes distinct suffixes for different tape-and-reel or cut-tape configurations. Confirm that the requested part matches the 4-AlphaDFN footprint dimensions and pinout requirements for your PCB layout. Cross-reference the manufacturer's latest datasheet to validate compliance with RoHS3 directives and REACH regulations before finalizing procurement specifications.

Selection Notes

Select this component when a dual N-channel solution is required within a minimal footprint constraint. The 20V rating suits low-voltage logic interfaces and battery management systems. Ensure the thermal design accommodates the 1.1W dissipation limit in the small DFN package. Compare gate charge and on-resistance parameters against single FET alternatives to evaluate switching speed and conduction loss trade-offs for the target application frequency.

Part Context

This part belongs to Alpha & Omega Semiconductor’s portfolio of green silicon MOSFETs, emphasizing compact packaging and high integration. The AOCA32112E serves as a dual-array alternative to discrete single FETs, reducing board space. It complements other AOCA series devices offering similar voltage ratings but varying current capacities or package types like SOIC-8.
