Overview
The DI048N03PTK-AQ is an N-channel Power MOSFET manufactured by Diotec Semiconductor, designed for surface-mount applications. It utilizes the 8-PowerVDFN (3x3) package and meets AEC-Q101 automotive qualification standards. The device features a drain-source voltage rating of 40 V and supports a continuous drain current of 48 A at case temperature. Key electrical characteristics include a maximum on-resistance of 7.6 mΩ at 10 V gate drive and a threshold voltage up to 2.5 V. Operating temperatures range from -55°C to +150°C junction temperature.
Feature Summary
- Automotive-grade reliability certified under AEC-Q101 standards
- Low on-resistance for efficient power switching in compact designs
- Enhanced thermal performance via 3x3 mm PowerQFN packaging
Applications
- Automotive power distribution systems
- DC-DC converter circuits
- Motor control applications
Procurement Notes
Verify the specific suffix 'K' against official Diotec documentation to confirm tape-and-reel packaging specifications. Ensure the part number matches the exact AEC-Q101 qualified variant. Cross-reference with authorized distributors to confirm current availability and lead times. Validate RoHS compliance status prior to integration into production schedules.
Selection Notes
Select this component for high-current automotive applications requiring low conduction losses. The 40V rating suits 12V or 24V nominal systems with transient protection needs. Consider the 3x3mm footprint for space-constrained PCB layouts. Verify gate drive voltage compatibility with the 7.6mΩ resistance specification to ensure optimal efficiency.
Part Context
This part belongs to Diotec's DI0XX series of automotive-qualified MOSFETs. It complements other devices like the DI048N04PT-AQ, differing primarily in voltage ratings or specific packaging variants within the same thermal and current capability class. The series targets robust performance in demanding automotive environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Diotec Semiconductor directly for approved equivalents or pin-compatible alternatives.
