BU15085S-E3/45

Bridge Rectifier Overview

The BU15085S-E3/45 is a single-phase bridge rectifier from Vishay's enhanced isoCink+™ series, designed for general-purpose AC/DC full-wave rectification. It features a maximum repetitive peak reverse voltage of 800 V and an average rectified forward current rating of 15 A at a case temperature of 80 °C. The device utilizes glass passivated chip junctions within a thin single in-line BU package. Key electrical characteristics include a typical thermal resistance (junction-to-case) of 2.5 °C/W and a maximum instantaneous forward voltage of 1.05 V at 7.5 A. It supports a non-repetitive peak forward surge current of 200 A and operates within a junction temperature range of -55 °C to +150 °C.

Bridge Rectifier Procurement Notes

Verify the specific part number suffix against official documentation to confirm exact ratings and compliance status. Confirm that the component meets RoHS requirements and JESD 201 class 1A whisker test standards if required by the design specifications. Ensure proper mounting torque limits are observed during assembly to maintain mechanical integrity.

Bridge Rectifier Selection Notes

Select this component based on the 800 V reverse voltage requirement and 15 A continuous current capability. Consider the thermal resistance values when designing heatsinking solutions, as performance varies significantly between free air and mounted conditions. Verify that the operating environment stays within the specified -55 °C to +150 °C junction temperature range.
