Procurement Notes
Verify the specific part number against official Vishay documentation to confirm compliance with RoHS standards and material categorization requirements. Ensure that the ordering suffix matches the required delivery mode and base quantity specifications provided in the manufacturer's ordering information section.
Selection Notes
Select this component when a standard 100 V rating is required alongside fast recovery characteristics. Confirm that the operating environment stays within the specified temperature limits and that the circuit design accommodates the 1.0 A continuous current rating and 30 A surge capacity.
Part Context
This component belongs to the 1N493x series of fast switching plastic rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different reverse voltage ratings, sharing common mechanical dimensions and electrical performance profiles optimized for general-purpose high-efficiency rectification tasks.
Replacement Considerations
Cross-reference with other manufacturers' 1N4934 equivalents or Vishay's 1N4933 through 1N4937 series members if voltage ratings differ. Verify pinout compatibility and thermal resistance values before substitution.
FAQ
