Bridge Rectifier Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Vishay General Semiconductor. Procurement should focus on identifying verified substitute parts or alternative manufacturers offering equivalent specifications. Verify that any replacement maintains the required 2A forward current and appropriate reverse voltage ratings for the specific application circuit design.

Bridge Rectifier Selection Notes

Select this component only if legacy compatibility is strictly required. For new designs, consider modern equivalents with similar 2A current ratings and comparable reverse voltage capabilities. Ensure the replacement supports through-hole assembly and meets necessary safety certifications such as UL 94V-0 flammability standards for the intended environment.

Bridge Rectifier Part Context

The 3N258 series belongs to Vishay's line of general-purpose bridge rectifiers. These components are engineered for robust performance in standard power applications. The E4 suffix indicates lead-free composition, aligning with environmental compliance standards. The KBP package type offers a compact solution for medium-current rectification tasks in various electronic systems.

Bridge Rectifier Replacement Considerations

Public confirmed substitutes include KBP08G and KBP208G. Verify that these alternatives match the original 2A current rating and 800V reverse voltage specification. Ensure the physical footprint and pinout compatibility are confirmed before integration into existing PCB layouts.
