AONS66415

Single FETs, MOSFETs Overview

The AONS66415 is an N-channel MOSFET from Alpha & Omega Semiconductor, utilizing AlphaSGT™ technology. It features a 40V drain-source voltage (Vdss) and supports continuous drain currents of 35A at ambient temperature (Ta) and 150A at case temperature (Tc). The device offers a maximum on-resistance (Rds(on)) of 2.5 milliohms at 20A with a 10V gate drive. Power dissipation ratings are 6.2W (Ta) and 131W (Tc). It operates within a junction temperature range of -55°C to 175°C and is housed in an 8-DFN (5x6) surface-mount package.

Single FETs, MOSFETs Procurement Notes

Verify the specific suffix or variant against the manufacturer's current datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and moisture sensitivity level (MSL) before integration into the assembly process. Cross-reference the ordering part number with official distributor catalogs to avoid discrepancies in packaging or revision levels.

Single FETs, MOSFETs Selection Notes

Select this component when low voltage drop and high current capacity are required in a small footprint. The 40V rating suits low-voltage systems, while the 150A case current capability supports high-load applications. Ensure thermal management strategies align with the 131W case dissipation rating to maintain reliability under peak load conditions.

Single FETs, MOSFETs Part Context

This device belongs to the AlphaSGT™ family of single N-channel MOSFETs designed for high-efficiency power switching. It replaces older planar technologies with trench structures to reduce conduction losses. The 8-DFN package provides improved thermal performance compared to standard SMD options, making it suitable for dense PCB layouts in modern electronic equipment.

Single FETs, MOSFETs Replacement Considerations

Check for direct substitutes such as the AONS66416 or similar AlphaSGT devices with compatible pinouts and electrical characteristics. Verify that any replacement maintains the same Vdss, Rds(on), and package dimensions to ensure mechanical and electrical interchangeability without redesigning the circuit board.
