Overview
The AON6908A is a dual asymmetric N-channel MOSFET in an 8-DFN (5x6) package. Q1 features VDS=30V, RDS(ON)<8.9mΩ at VGS=10V, and ID=46A. Q2 is an SRFET with VDS=30V, RDS(ON)<3.6mΩ at VGS=10V, and ID=80A. It includes an integrated Schottky diode on Q2. The device supports logic-level gate drive, operates from -55°C to 150°C, and is rated for 100% UIS testing.
Feature Summary
- Dual asymmetric configuration integrating a high-side switching FET and a low-side SRFET within a single compact Power DFN5x6 package.
- Integrated Schottky diode on the low-side channel provides low reverse recovery charge and forward voltage to minimize switching losses.
- Optimized layout and board space utilization designed specifically for high-efficiency synchronous buck power stages.
Applications
- Compact DC/DC converter applications
- Synchronous buck power stage design
Procurement Notes
Verify component authenticity through authorized Alpha & Omega Semiconductor channels or certified distributors. Confirm datasheet revision and lot traceability upon receipt. Ensure storage conditions comply with MSL ratings to prevent moisture damage prior to soldering.
Selection Notes
Select this part for designs requiring optimized thermal performance and reduced footprint in synchronous rectification topologies. Evaluate thermal resistance parameters against specific PCB copper area and airflow constraints to ensure junction temperature limits are not exceeded during operation.
Part Context
This component belongs to the AON690 series of dual asymmetric N-channel MOSFETs manufactured by Alpha & Omega Semiconductor. It shares the same package type and general application scope as related parts like the AON6906A, but offers distinct current handling and on-resistance characteristics tailored for specific power density requirements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameter margins before considering any alternative components.
