BU2010-E3/51

Bridge Rectifier Overview

The BU2010-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 1000 V and an average rectified forward current of 20 A at a case temperature of 61 °C. The device supports a non-repetitive peak forward surge current of 240 A with a rating for fusing of 239 A²s. Electrical characteristics include a typical junction capacitance of 95 pF and a maximum instantaneous forward voltage of 1.05 V at 10 A. Thermal resistance values are 2.4 °C/W (junction-to-case) and 20 °C/W (junction-to-ambient). The component operates within a temperature range of -55 °C to +150 °C.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix to confirm packaging details. The /51 suffix indicates delivery in paper trays with a base quantity of 250 units per tray. Confirm RoHS compliance status based on the E3 designation. Ensure the procurement channel provides official datasheet documentation for technical validation before integration into designs.

Bridge Rectifier Selection Notes

Select this component when a 1000 V reverse voltage rating is required for general-purpose rectification. Consider the thermal management requirements, as the average current derates significantly without a heatsink. Verify that the application environment stays within the specified operating junction and storage temperature limits of -55 °C to +150 °C.

Bridge Rectifier Part Context

This part belongs to the BU2006, BU2008, and BU2010 series of Enhanced isoCink+™ Bridge Rectifiers. All variants share identical mechanical dimensions and electrical characteristics except for the maximum repetitive peak reverse voltage, which varies across the series. The BU2010 specifically offers the highest voltage rating of 1000 V within this family.

Bridge Rectifier Replacement Considerations

Direct replacements within the same Vishay series include BU2006 and BU2008, provided the lower voltage ratings meet the circuit requirements. Cross-brand substitutions require matching the 20 A current rating, 1000 V reverse voltage, and BU package footprint.
