BU10105S-E3/45

Bridge Rectifier Overview

The BU10105S-E3/45 is a single-phase bridge rectifier from the Vishay BU1006, BU1008, and BU1010 series. It features a maximum repetitive peak reverse voltage of 1000 V and an average rectified forward current of 10 A at a case temperature of 92 °C. The device utilizes glass passivated chip junctions within a thin single in-line BU package. Electrical characteristics include a maximum instantaneous forward voltage of 1.05 V at 5.0 A and a maximum reverse current of 5.0 μA at rated voltage. Thermal resistance values are 3.0 °C/W (junction-to-case) and 20 °C/W (junction-to-ambient).

Bridge Rectifier Feature Summary

• Glass passivated chip junction for enhanced reliability.
• Thin single in-line package design with superior thermal conductivity.
• UL recognition file number E312394 for safety compliance.

Bridge Rectifier Applications

• AC/DC bridge full wave rectification for switching power supplies.
• Home appliances.
• White-goods applications.

Bridge Rectifier Procurement Notes

Verify component authenticity by checking the manufacturer's marking code against official documentation. Confirm RoHS compliance status via the specific ordering suffix. Ensure proper handling procedures are followed during installation to maintain the integrity of the glass passivated junctions and solderable matte tin plated leads.

Bridge Rectifier Selection Notes

Select this component based on the required 1000 V reverse voltage rating and 10 A continuous current capacity. Evaluate thermal management requirements using the specified thermal resistance values to ensure operation within the -55 °C to +150 °C junction temperature range. Verify that the BU package dimensions fit the intended PCB layout constraints.

Bridge Rectifier Part Context

This part belongs to the BU1006, BU1008, and BU1010 family of Enhanced isoCink+™ Bridge Rectifiers. The series offers standardized electrical ratings differentiated primarily by their maximum repetitive peak reverse voltage capabilities, ranging from 600 V to 1000 V, while maintaining consistent current and thermal performance characteristics across the lineup.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same series include BU1006-E3/45 and BU1008-E3/45, provided the lower voltage ratings are sufficient for the application. Cross-manufacturer replacements must match the 10 A current, 1000 V voltage, and BU package footprint specifications.

Bridge Rectifier FAQ

What is the maximum surge current capability?

The non-repetitive peak forward surge current (IFSM) is rated at 120 A for an 8.3 ms single sine-wave pulse at TJ = 25 °C.

Is the device suitable for floating ground applications?

Yes, but Vishay recommends using an insulator to meet safety requirements if the device is mounted in a Floating Ground (F.G.) application.

What is the dielectric strength for safety use?

The device is UL approved for safety use with a dielectric strength of 1500 V.
