Overview
The AON6884L is a dual N-channel MOSFET from Alpha & Omega Semiconductor, housed in an 8-DFN (5x6) package. It features a drain-source voltage of 40V and a continuous drain current of 13A at case temperature. The device exhibits a maximum on-resistance of 7.8mΩ at 10V gate drive. Thermal performance includes a power dissipation of 1.95W at ambient and 35W at case temperatures. Operating junction temperature ranges from -55°C to 150°C.
Feature Summary
- Dual N-channel configuration for space-efficient circuit design
- Low on-resistance for improved power efficiency
- Surface-mount DFN package for compact PCB integration
Applications
- DC-DC converter synchronous rectification
- Load switching applications
- Power management circuits
Procurement Notes
Verify the specific suffix 'L' against the official Alpha & Omega Semiconductor datasheet to confirm pinout and electrical specifications match the target application. Ensure the 8-DFN (5x6) footprint aligns with the PCB layout requirements. Confirm RoHS compliance status through the manufacturer's documentation before procurement.
Selection Notes
Select this component when a dual N-channel solution is required in a small form factor. The 40V rating suits low-voltage DC systems. Evaluate thermal constraints carefully, as the 8-DFN package relies heavily on PCB copper area for heat dissipation. Compare on-resistance values against system efficiency targets.
Part Context
This part belongs to Alpha & Omega Semiconductor's dual MOSFET portfolio. It shares the 8-DFN (5x6) package format with other devices in the series. The 'L' suffix typically denotes specific manufacturing lot or packaging variations within the same electrical family. Verify compatibility with existing designs using similar dual FETs.
Replacement Considerations
Potential substitutes include AO4884 and AON6812. Verify that replacement parts maintain compatible voltage ratings, current capabilities, and package dimensions. Ensure thermal characteristics and switching speeds meet the original design requirements.
