AONX36322

Overview

The AONX36322 is a dual N-channel Power MOSFET from Alpha & Omega Semiconductor, designed for low-voltage applications. It features a 30V drain-source voltage rating and supports a continuous drain current of 21A at case temperature. The device utilizes an asymmetric configuration within an 8-DFN package (3.3x3.3mm). Key electrical characteristics include a maximum gate threshold voltage of 1.9V at 250µA and a typical gate charge of 29nC at 10V. The input capacitance is specified at 1330pF at 15V. Thermal performance allows for a power dissipation of up to 33W at case temperature and 3.4W at ambient temperature, with an operating junction temperature range of -55°C to 150°C.

Feature Summary

• Dual N-channel asymmetric configuration optimized for high-current switching
• Low gate threshold voltage enabling efficient drive from standard logic levels
• Compact 8-DFN exposed pad package for enhanced thermal dissipation
• Designed for low-voltage power management and motor control applications

Applications

• DC-DC converter synchronous rectification
• Motor driver circuits for consumer electronics
• Power distribution in portable devices
• Battery protection and load switch applications

Procurement Notes

Verify the specific suffix or tape/reel configuration required for your assembly line. Confirm that the 8-DFN footprint matches your PCB design guidelines, particularly regarding the exposed pad thermal connection. Ensure that the supply chain source provides valid manufacturer traceability documentation to guarantee component authenticity and quality standards.

Selection Notes

Select this component when a dual N-channel solution is required for 30V systems with moderate current demands. The asymmetric nature suggests it may be intended for specific half-bridge or buck converter topologies where distinct upper and lower switch characteristics are beneficial. Compare total gate charge and on-resistance against competitors if switching frequency efficiency is critical.
