KBU6G-E4/51

Overview

The KBU6G-E4/51 is a single-phase bridge rectifier diode manufactured by Vishay. It utilizes silicon semiconductor material and is housed in a plastic KBU case with four pins. The device supports an average forward current of 6 A and withstands a repetitive peak reverse voltage of 400 V. It features a maximum non-repetitive peak forward surge current of 300 A. The component operates within a temperature range from -50°C to +150°C, with a maximum forward voltage of 1 V and a peak reverse current of 5 μA.

Feature Summary

• Integrated four-element bridge configuration for single-phase rectification
• Isolated case design for thermal management and electrical safety
• Lead-free construction compliant with RoHS standards

Applications

• AC to DC power supply conversion circuits
• General-purpose rectification in industrial equipment
• Battery charging systems requiring moderate current handling

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm pinout orientation and marking codes. Ensure the procurement channel provides traceable datasheets matching the KBU6G designation. Confirm compliance certifications such as UL recognition are documented for the specific batch. Validate that the component meets the required environmental operating temperatures for the intended application environment.

Selection Notes

Select this component when a 6 A continuous current rating and 400 V blocking voltage are required in a through-hole KBU package. Compare the 300 A surge capability against expected inrush currents in the target circuit. Consider the 150°C junction temperature limit for high-temperature environments. Evaluate the physical dimensions of the KBU case for PCB layout constraints relative to alternative packages.

Part Context

This part belongs to the Vishay KBU6 series of bridge rectifiers, designed for general-purpose applications. The series offers various voltage ratings while maintaining a consistent 6 A current capacity and KBU footprint. The E4/51 suffix indicates lead-free termination and specific packaging details defined by the manufacturer.

Replacement Considerations

Cross-reference with other Vishay KBU6 variants such as KBU6D or KBU6H if different voltage ratings are acceptable. Verify mechanical compatibility with existing footprints before substituting with components from other manufacturers.
