BU1506-E3/51

Bridge Rectifier Overview

The BU1506-E3/51 is a single-phase bridge rectifier from Vishay General Semiconductor, utilizing Enhanced isoCink+ technology. It features a maximum repetitive peak reverse voltage of 600 V and an average rectified forward current of 15 A at a case temperature of 80 °C. The device has a non-repetitive peak forward surge current rating of 200 A and a typical junction-to-case thermal resistance of 2.5 °C/W. 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 rated voltage. It operates within a junction and storage temperature range of -55 to +150 °C.

Bridge Rectifier Feature Summary

Bridge Rectifier Procurement Notes

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

Bridge Rectifier Selection Notes

Select this component based on the required 600 V reverse voltage rating and 15 A continuous current capability. Ensure the application allows for adequate heat sinking or free air derating to maintain the junction temperature within the specified -55 to +150 °C operating range. Verify mechanical mounting torque limits during installation.

Bridge Rectifier Part Context

This component belongs to the BU1506, BU1508, and BU1510 series of Enhanced isoCink+ Bridge Rectifiers. These devices share the same physical package and general electrical architecture but differ in their maximum repetitive peak reverse voltage ratings. The BU1506 specifically provides the 600 V rating variant within this family.

Bridge Rectifier Replacement Considerations

Direct replacements within the same Vishay series include BU1508 (800 V) and BU1510 (1000 V), provided the higher voltage ratings are acceptable for the circuit design. Other manufacturers' bridge rectifiers must be evaluated for matching current, voltage, and thermal specifications.
