UD8KB80-BP

Bridge Rectifier Overview

The MCC UD8KB80-BP is a single-phase glass passivated bridge rectifier rated for an average forward current of 8 A and a peak repetitive reverse voltage of 800 V. It utilizes a D3K surface-mount package with solder pad termination. Key electrical parameters include a maximum forward voltage of 1.0 V at 4 A, a reverse leakage current of 5 µA at 25°C, and a non-repetitive peak surge current capability of 175 A under 8.3 ms half-sine wave conditions. The device operates within a junction temperature range of -55°C to +150°C.

Bridge Rectifier Feature Summary

• Glass passivated chip junction construction
• High surge forward current capability
• Epoxy material meets UL 94 V-0 flammability rating

Bridge Rectifier Applications

• General purpose AC to DC power supply conversion
• Bridge rectifier circuits in consumer electronics
• Industrial control system power stages

Bridge Rectifier Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors. Counterfeit components are prevalent; unauthorized sources lack traceability and warranty coverage. Confirm the "BP" suffix indicates RoHS compliance and halogen-free status. Ensure the D3K package dimensions match the target PCB footprint before finalizing orders.

Bridge Rectifier Selection Notes

Select this component when an 8 A continuous current and 800 V blocking voltage are required in a compact surface-mount form factor. The D3K package facilitates automated assembly. Verify thermal management requirements, as the junction-to-ambient resistance is 55 °C/W without a heatsink. Consider derating curves for high ambient temperature environments to maintain reliability.

Bridge Rectifier Part Context

This part belongs to the UD8KB series, which covers ratings from 50 V to 1000 V. The UD8KB80 specifically targets applications requiring 800 V isolation. It shares the same physical D3K package and general characteristics with other variants in the family, differing primarily in voltage ratings and marking codes.

Bridge Rectifier Replacement Considerations

Direct substitutes include the GBJA806-BP (8 A, 600 V) if voltage headroom allows, or the UD8KB100-BP (8 A, 1000 V) for higher voltage margins. Ensure the replacement maintains the D3K package and pinout compatibility.
