KBL10-E4/51

Overview

The KBL10-E4/51 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It features an average forward current of 1 A and a maximum repetitive peak reverse voltage of 1000 V. The device utilizes a plastic encapsulation in the KBL package, designed for screw mounting with solder pin terminations. Key electrical parameters include a forward voltage drop of 1.1 V at rated current and a non-repetitive peak forward surge current capability of 30 A. The component operates within a temperature range from -55 °C to +150 °C junction temperature.

Feature Summary

• Single-phase bridge rectifier configuration
• Screw mount installation style
• Plastic encapsulated construction

Applications

• General purpose rectification

• DC output conversion

Procurement Notes

Verify the specific manufacturer designation as Vishay Semiconductors or Vishay General Semiconductor based on the latest datasheet revision. Confirm RoHS compliance status via official documentation. Ensure the ordering suffix matches the required termination and packaging specifications for your assembly process.

Selection Notes

Select this component when a 1 A continuous current rating and 1000 V blocking voltage are required. The KBL package supports screw mounting, which is suitable for applications needing robust mechanical fixation. Verify thermal management requirements against the specified junction temperature limits.

Part Context

This part belongs to the KBL series of bridge rectifiers from Vishay. The series offers various voltage ratings for 1 A applications. The E4 suffix typically indicates lead-free composition compliant with EU directives. The /51 suffix denotes bulk packaging.

Replacement Considerations

Direct replacements must match the 1 A current, 1000 V voltage, and KBL package dimensions. Verify pinout compatibility and thermal characteristics before substitution.
