BU1210-M3/51

Bridge Rectifier Overview

The BU1210-M3/51 is a single-phase bridge rectifier from Vishay General Semiconductor, utilizing enhanced isoCink+ technology. It features a maximum repetitive peak reverse voltage of 1000 V and an average rectified forward current of 12 A at a case temperature of 85 °C. The device has a non-repetitive peak forward surge current rating of 150 A and a typical junction capacitance of 50 pF. Operating within a temperature range of -55 to +150 °C, it employs a thin single in-line package with glass passivated chip junctions.

Bridge Rectifier Feature Summary

• Glass passivated chip junctions for superior reliability
• Thin single in-line package design
• UL recognition file number E312394

Bridge Rectifier Applications

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

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status. The M3 suffix indicates halogen-free, RoHS-compliant commercial grade material categorization. Confirm that the /51 delivery mode matches the required paper tray packaging specifications before finalizing procurement orders.

Bridge Rectifier Selection Notes

Select this component when a 1000 V blocking capability is required alongside a 12 A continuous current rating. Ensure thermal management aligns with the specified derating curves for free air or heatsink-mounted operation. Verify that the operating junction temperature remains within the -55 to +150 °C range during application testing.

Bridge Rectifier Part Context

This part belongs to the BU1206, BU1208, and BU1210 series of enhanced isoCink+ bridge rectifiers. The series shares identical mechanical dimensions and general electrical characteristics, differentiated primarily by their maximum repetitive peak reverse voltage ratings of 600 V, 800 V, and 1000 V respectively.

Bridge Rectifier Replacement Considerations

Direct substitutes include other Vishay BU1210 variants such as the BU1210-E3/51. Cross-manufacturer replacements require matching the 1000 V reverse voltage, 12 A forward current, and BU case style dimensions.
