BU1508-E3/45

Bridge Rectifier Overview

The BU1508-E3/45 is a single-phase bridge rectifier from Vishay General Semiconductor, rated for a maximum repetitive peak reverse voltage of 800 V and an average forward current of 15 A. It utilizes the enhanced isoCink+™ technology in a thin single-in-line BU package. The device features glass passivated chip junctions and matte tin plated leads compliant with RoHS directives. Key electrical characteristics include a non-repetitive peak forward surge current of 200 A, a typical thermal resistance (junction-to-case) of 2.5 °C/W, and a maximum operating junction temperature of 150 °C.

Bridge Rectifier Feature Summary

• Enhanced isoCink+™ technology providing superior thermal conductivity
• Glass passivated chip junction for improved reliability
• Thin single-in-line package design optimized for printed circuit boards

Bridge Rectifier Applications

• AC/DC bridge full wave rectification for switching power supplies
• Rectification circuits in home appliances
• White-goods applications

Bridge Rectifier Procurement Notes

Verify component authenticity by checking the manufacturer's marking on the device body against official datasheet specifications. Confirm compliance status through the E3 suffix, which indicates RoHS compliance. Ensure that the ordering information matches the required voltage rating and package type to avoid substitution errors during procurement.

Bridge Rectifier Selection Notes

Select this component when an 800 V blocking capability is required alongside a 15 A continuous current rating. Consider the BU package dimensions for PCB layout constraints and evaluate the thermal resistance values if heatsinking is necessary for high ambient temperatures or elevated duty cycles.

Bridge Rectifier Part Context

This part belongs to the BU1506, BU1508, and BU1510 series, differentiated primarily by their peak reverse voltage ratings of 600 V, 800 V, and 1000 V respectively. All variants share identical current ratings, package styles, and thermal characteristics within the enhanced isoCink+™ family.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same series include the BU1506-E3/45 and BU1510-E3/45, provided the voltage requirements align with 600 V or 1000 V ratings respectively.
