KBU8K-E4/51

Overview

The KBU8K-E4/51 is a single-phase bridge rectifier from Vishay's KUB8 series, housed in a KBU through-hole package. It features a peak repetitive reverse voltage (Vrrm) of 800 V and an average forward rectified current (If) of 8 A per diode. The component supports a peak non-repetitive forward surge current (Ifsm) of 300 A. Electrical characteristics include a maximum peak forward voltage (Vf) of 1 V and a peak reverse current (Ir) of 10 μA. It operates within a junction temperature range of -50°C to +150°C.

Feature Summary

Glass passivated junction for enhanced environmental stability
High surge current capability for robust transient protection
Low forward voltage drop for improved efficiency

Applications

AC-DC power supply circuits
Battery charging systems
General-purpose rectification in industrial equipment

Procurement Notes

Verify the complete part number including suffixes such as /51 against official Vishay documentation to ensure correct packaging and compliance specifications. Confirm that the KBU package dimensions match the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when an 800 V reverse voltage rating is required alongside an 8 A continuous current capacity. Ensure the application environment remains within the specified -50°C to +150°C operating temperature range. Verify that the 300 A surge current rating exceeds the expected inrush currents in the circuit design.

Part Context

This device belongs to the KUB8 series of single-phase bridge rectifiers manufactured by Vishay General Semiconductor. The series utilizes glass passivation technology and is designed for general-purpose applications requiring reliable rectification in compact through-hole configurations.

Replacement Considerations

Cross-reference with other Vishay KBU8 variants sharing identical electrical parameters but differing only in voltage ratings or suffix codes. Verify pinout compatibility and thermal performance before substituting.
