Procurement Notes
Verify the specific ordering suffix when sourcing this component. Suffixes such as TR indicate tape and reel packaging, while their absence denotes box packaging. Confirm lead-free status via the PbF suffix if required by assembly specifications. Ensure the manufacturer documentation matches the requested configuration before procurement.
Selection Notes
Select this component for applications requiring small footprints and low forward voltage drops. Verify thermal management requirements against the junction-to-ambient thermal resistance of 80 °C/W. Consider the peak surge current rating of 430 A for transient protection scenarios. Ensure the operating environment stays within the specified -55 °C to 150 °C junction temperature range.
Part Context
This part belongs to the Vishay Schottky Q Series, designed for industrial level applications. The product line was acquired by Vishay Intertechnology, Inc., following the acquisition of International Rectifier’s Power Control Systems business in April 2007. The datasheet serves as the primary technical reference for electrical characteristics and mechanical dimensions.
Replacement Considerations
