BU1510-M3/45

Bridge Rectifier Overview

The BU1510-M3/45 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 forward current rating of 15 A at a case temperature of 80 °C. The device operates with a non-repetitive peak forward surge current of 200 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 7.5 A and a maximum reverse current of 5 μA at 25 °C. 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 attributes. The M3 suffix indicates halogen-free, RoHS-compliant commercial grade material. Confirm that the /45 packaging code corresponds to tube delivery with a base quantity of 20 units. Ensure all technical parameters meet the requirements of the target application before finalizing procurement.

Bridge Rectifier Selection Notes

Select this component when a 1000 V blocking capability is required for single-phase rectification. The 15 A average current rating supports high-power designs when mounted on appropriate heatsinks. Consider the 2.5 °C/W thermal resistance for junction-to-case cooling strategies. Verify that the operating environment stays within the specified -55 °C to +150 °C temperature range for reliable performance.

Bridge Rectifier Part Context

This part belongs to the BU15 series of enhanced isoCink+ bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings, specifically the BU1506 (600 V) and BU1508 (800 V). All models share identical physical dimensions and current handling capabilities, differing only in their maximum repetitive peak reverse voltage specifications.

Bridge Rectifier Replacement Considerations

Direct replacements within the same family include the BU1510-E3/45 variant, which shares identical electrical and mechanical specifications but differs in environmental compliance markings. Cross-brand substitutions require matching the 1000 V reverse voltage, 15 A forward current, and BU package footprint.
