BU2510-E3/45

Bridge Rectifier Overview

The BU2510-E3/45 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 25 A at a case temperature of 60 °C. The device operates with a non-repetitive peak forward surge current of 300 A and maintains a junction temperature range from -55 °C to +150 °C. Electrical characteristics include a maximum instantaneous forward voltage of 1.05 V at 12.5 A and a maximum reverse current of 5 μA at rated voltage. The component is housed in a thin single-in-line BU package with matte tin-plated leads.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status and packaging type. The base part number indicates RoHS-compliant commercial grade construction. Confirm that the terminal plating meets solderability requirements per J-STD-002 and JESD 22-B102 standards before finalizing procurement specifications.

Bridge Rectifier Selection Notes

Select this component based on the required 1000 V reverse voltage rating and 25 A continuous current capacity. Ensure adequate heatsinking is provided to maintain the case temperature within limits for the specified current derating curves. Verify that the mounting torque does not exceed the recommended 5.7 cm-kg or the maximum 10 cm-kg limit.

Bridge Rectifier Part Context

This component belongs to the BU2506, BU2508, and BU2510 series of enhanced isoCink+ bridge rectifiers. The series shares common mechanical dimensions and thermal 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 within the same series include BU2506-E3/45 and BU2508-E3/45, which share identical packages and current ratings but offer lower reverse voltage capabilities.
