BU1506-M3/45

Bridge Rectifier Overview

The BU1506-M3/45 is a single-phase bridge rectifier from Vishay's Enhanced isoCink+™ series, rated for a maximum repetitive peak reverse voltage of 600 V and an average forward current of 15 A. It features a typical instantaneous forward voltage of 0.87 V at 7.5 A and a non-repetitive peak forward surge current capability of 200 A. The device utilizes glass passivated chip junctions within a thin single in-line BU package, offering a thermal resistance of 2.5 °C/W (junction-to-case) and operating across a temperature range of -55 to +150 °C.

Bridge Rectifier Feature Summary

• Enhanced isoCink+™ technology providing superior thermal conductivity
• Glass passivated chip junctions for improved reliability
• Thin single in-line package design optimized for automated placement

Bridge Rectifier Applications

• General purpose AC/DC bridge full wave rectification
• Switching power supply circuits
• Home appliances and 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 /45 packaging code corresponds to tube delivery with a base quantity of 20 units per tube as specified in the manufacturer's ordering information.

Bridge Rectifier Selection Notes

Select this component when a 600 V rating is required for general-purpose rectification. Ensure the application can accommodate the 15 A average forward current limit under appropriate thermal conditions. Consider the BU package dimensions and mounting torque specifications during PCB layout and mechanical assembly planning.

Bridge Rectifier Part Context

This part belongs to the BU15xx family of enhanced bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different reverse voltage ratings, such as the BU1508 (800 V) and BU1510 (1000 V), all sharing identical current ratings and physical package characteristics.

Bridge Rectifier Replacement Considerations

Direct substitutes include BU1508-M3/45 and BU1510-M3/45 if higher reverse voltage ratings are acceptable. Verify that alternative components match the BU package outline dimensions and pinout configuration to ensure compatibility with existing board layouts.
