BU2006-M3/51

Bridge Rectifier Overview

The BU2006-M3/51 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 rating of 20 A at a case temperature of 61 °C. The device has a non-repetitive peak forward surge current capability of 240 A and a typical junction-to-case thermal resistance of 2.4 °C/W. Electrical characteristics include a maximum instantaneous forward voltage of 1.05 V at 10 A and a maximum reverse current of 5 μA at rated voltage. Operating temperatures range from -55 °C to +150 °C.

Bridge Rectifier Feature Summary

• Enhanced isoCink+ technology provides superior thermal conductivity for efficient heat dissipation.
• Glass passivated chip junction ensures stability and reliability under various operating conditions.
• Thin single in-line package design facilitates compact circuit board layout.

Bridge Rectifier Applications

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix to confirm compliance requirements. The M3 suffix indicates halogen-free, RoHS-compliant commercial grade material. Confirm the delivery mode matches project needs, as the /51 suffix corresponds to paper tray packaging with a base quantity of 250 units. Ensure mounting torque specifications are adhered to during assembly.

Bridge Rectifier Selection Notes

Select this component when a 600 V blocking voltage and 20 A continuous current capacity are required. Consider the thermal resistance values if heatsinking is necessary for operation above ambient temperatures. Verify that the application does not exceed the 240 A surge current limit. Compare against BU2008 or BU2010 variants if higher voltage ratings are needed.

Bridge Rectifier Part Context

This part belongs to the BU2006, BU2008, and BU2010 family of Enhanced isoCink+ Bridge Rectifiers. All variants share identical mechanical dimensions and current ratings but differ in their maximum repetitive peak reverse voltage capabilities. The BU2006 specifically offers the 600 V rating within this series.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same Vishay family include the BU2008 (800 V) and BU2010 (1000 V), provided the voltage rating exceeds the circuit requirements. Other manufacturers' bridge rectifiers must be evaluated for matching current, voltage, and thermal performance characteristics.
