Bridge Rectifier Procurement Notes

Verify the complete ordering part number, including suffixes such as -E4/51, to ensure correct compliance status and packaging configuration. Confirm that the specified voltage and current ratings align with the specific circuit requirements before procurement. Cross-reference the document number 88534 for the most current technical specifications and mechanical data.

Bridge Rectifier Selection Notes

Select this component for general-purpose rectification where a 600 V reverse voltage rating and 0.9 A average current are sufficient. Consider the thermal resistance values when designing heat dissipation strategies for enclosed environments. Ensure the PCB layout accommodates the WOG package dimensions and lead spacing for proper mechanical stability and soldering.

Bridge Rectifier Part Context

This component belongs to the BxxxC800G series of glass-passivated single-phase bridge rectifiers from Vishay Semiconductors. The series includes variants with different voltage ratings, such as B40C800G (65 V), B80C800G (125 V), B125C800G (200 V), and B250C800G (400 V). All variants share similar physical characteristics and electrical performance profiles regarding current handling and forward voltage drop.

Bridge Rectifier Replacement Considerations

Direct replacements within the same Vishay family include B40C800G, B80C800G, B125C800G, and B250C800G, provided the lower voltage ratings meet the circuit's peak reverse voltage requirements. Verify that alternative manufacturers' components match the WOG package outline and terminal configurations for direct footprint compatibility.
