DB103-BP

Bridge Rectifier Overview

The DB103-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a 1.0 A average forward rectified current rating and a 200 V maximum repetitive peak reverse voltage. The device utilizes glass passivated silicon junctions for reliability. Key electrical parameters include a maximum non-repetitive peak forward surge current of 50 A, a typical forward voltage drop of 1.1 V at rated current, and a maximum RMS isolation voltage of 4000 V. It operates within a temperature range of -55 °C to +150 °C.

Bridge Rectifier Feature Summary

• Glass passivated junction construction ensures high reliability and stability under varying thermal conditions.
• Molded plastic case provides mechanical robustness with UL flammability classification 94V-0.
• Designed for printed circuit board mounting with polarity symbols molded directly on the body.

Bridge Rectifier Applications

• General purpose AC to DC power supply rectification
• Battery charging circuits
• Low voltage DC power supplies

Bridge Rectifier Procurement Notes

Verify component authenticity through official MCC channels or authorized distributors. Confirm RoHS compliance status and check for recent Product Change Notifications (PCNs) regarding manufacturing site or material updates. Ensure the specific suffix matches required packaging options.

Bridge Rectifier Selection Notes

Select this component when a 1 A current capacity and 200 V blocking voltage are sufficient for the application. Consider the DB-1 package dimensions for PCB layout constraints. Evaluate thermal management requirements based on the specified junction temperature limits and ambient operating conditions.

Bridge Rectifier Part Context

This part belongs to the MCC DB series of single-phase bridge rectifiers. The series offers various voltage ratings from 50 V to 1000 V while maintaining a consistent 1.0 A current rating. The DB103-BP specifically addresses low-voltage applications requiring reliable rectification in compact through-hole packages.

Bridge Rectifier Replacement Considerations

Cross-reference with other manufacturers' DB103 equivalents such as Rectron DB103S-T or generic 1A 200V bridge rectifiers. Verify pinout compatibility and physical footprint alignment before substitution. Ensure equivalent surge current ratings and forward voltage characteristics match design specifications.
