Overview
The Vishay 10WQ045FN is a surface-mount Schottky rectifier in the D-PAK (TO-252AA) package. It features an average forward current rating of 10 A and a maximum repetitive peak reverse voltage of 45 V. The device supports high-frequency operation with a low forward voltage drop of 0.630 V at 10 A and 25 °C. It includes a guard ring for enhanced ruggedness and long-term reliability, operating within a junction temperature range of -40 to 175 °C.
Feature Summary
- Low forward voltage drop for improved efficiency
- Guard ring structure for enhanced ruggedness and reliability
- High frequency operation capability
- Small footprint surface mount design
Applications
- Disk drives
- Switching power supplies
- Converters
- Free-wheeling diodes
- Battery charging circuits
- Reverse battery protection
Procurement Notes
Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging orientation and lead-free status. Confirm that the component meets AEC-Q101 Level qualification requirements if automotive application standards are necessary. Ensure thermal management aligns with the specified junction-to-case and junction-to-ambient resistance values during system integration.
Selection Notes
Select this component when a compact surface-mount solution is required for moderate current applications up to 10 A. The low forward voltage drop makes it suitable for improving efficiency in switching power supplies and converters. Verify that the 45 V reverse voltage rating provides adequate margin for the specific circuit operating conditions.
Part Context
This part belongs to the Vishay Schottky Q Series, designed specifically for applications requiring low forward drop and small footprints on printed circuit boards. The product was originally developed by International Rectifier before being acquired by Vishay Intertechnology, Inc., as part of its acquisition of International Rectifier’s Power Control Systems business.
Replacement Considerations
Check datasheets for alternative Schottky rectifiers in the TO-252AA package with matching 10 A and 45 V ratings. Ensure any substitute maintains similar forward voltage characteristics and thermal resistance values to preserve original circuit performance and reliability.
