AON6448

Single FETs, MOSFETs Overview

The AON6448 is an N-channel MOSFET from Alpha & Omega Semiconductor, designed for surface-mount applications. It features a drain-source voltage (Vdss) of 80V and is housed in an 8-DFN (5x6) package. The device supports a continuous drain current of 11A at ambient temperature and 65A at case temperature. Key electrical parameters include a maximum on-resistance (Rds(on)) of 2.5 milliohms at Vgs=10V. Power dissipation ratings are specified as 2.5W at Ta and 83W at Tc. The component operates within a junction temperature range of -55°C to 175°C.

Single FETs, MOSFETs Procurement Notes

Verify the specific suffix code on the ordering part number to confirm exact packaging configuration and tape-and-reel specifications. Ensure compatibility with RoHS3 compliance requirements if mandated by your assembly standards. Cross-reference the manufacturer's latest datasheet revision to confirm pinout integrity and thermal pad dimensions before finalizing PCB footprint design.

Single FETs, MOSFETs Selection Notes

Select this component when an 80V rating is required alongside low conduction losses. The 8-DFN form factor offers a balance between thermal dissipation and board space efficiency. Consider the 11A/65A current derating curves based on your specific heatsinking strategy and ambient operating conditions to ensure reliable long-term operation under load.

Single FETs, MOSFETs Part Context

This part belongs to Alpha & Omega Semiconductor’s SDMOS series, which focuses on high-performance power switching solutions. The 8-DFN package is commonly used in modern electronics where miniaturization is critical. It serves as a robust alternative to larger through-hole packages while maintaining comparable electrical performance for medium-power applications.

Single FETs, MOSFETs Replacement Considerations

Check for direct pin-compatible substitutes within the same 80V N-channel category. Verify that any replacement maintains or exceeds the 2.5mΩ Rds(on) and 83W Tc power dissipation ratings. Ensure the new component fits the existing 8-DFN (5x6) footprint without mechanical interference.
