BU1510-M3/51

Bridge Rectifier Overview

The BU1510-M3/51 is a single-phase bridge rectifier from Vishay General Semiconductor, rated for a maximum repetitive peak reverse voltage of 1000 V and an average forward current of 15 A. It utilizes enhanced isoCink+ technology within a thin single in-line (BU) package. The device features glass passivated chip junctions and matte tin plated leads. Electrical characteristics include a maximum instantaneous forward voltage of 1.05 V at 7.5 A and a typical thermal resistance of 2.5 °C/W (junction-to-case). Operating temperatures range from -55 °C to +150 °C.

Bridge Rectifier Feature Summary

• Enhanced isoCink+ technology providing superior thermal conductivity
• Glass passivated chip junctions for reliability
• Thin single in-line package design
• UL recognition file number E312394

Bridge Rectifier Applications

• General purpose AC/DC bridge full wave rectification
• Switching power supplies
• Home appliances
• White-goods applications

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance attributes. The M3 suffix indicates halogen-free, RoHS-compliant commercial grade material categorization. Confirm that the /51 delivery mode corresponds to paper tray packaging with a base quantity of 250 units as specified in the manufacturer's ordering information section.

Bridge Rectifier Selection Notes

Select this component when a 1000 V blocking capability is required for general-purpose rectification. Ensure the application can accommodate the 15 A average forward current rating or apply appropriate derating based on case temperature. Verify that the mounting torque does not exceed 10 cm-kg and consider the 2.5 mm minimum heatsink clearance if utilizing forced air cooling.

Bridge Rectifier Part Context

This part belongs to the BU1506, BU1508, and BU1510 series of enhanced isoCink+ bridge rectifiers. All variants share identical mechanical dimensions, thermal characteristics, and current ratings, differing only in their maximum repetitive peak reverse voltage ratings of 600 V, 800 V, and 1000 V respectively.

Bridge Rectifier Replacement Considerations

Direct functional equivalents within the same Vishay family include the BU1506-E3/51 and BU1508-E3/51. These parts share the same BU package and 15 A current rating but offer lower reverse voltage capabilities of 600 V and 800 V respectively.
