KBU6B-M3/P

Overview

The KBU6B-M3/P is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes silicon components housed in the KBU plastic case with four pins. The device supports an average forward rectified current of 6 A and offers a maximum repetitive peak reverse voltage of 100 V. Key electrical parameters include a non-repetitive peak forward surge current of 250 A, a maximum DC blocking voltage of 100 V, and a maximum RMS voltage of 70 V. The unit operates within a temperature range of -55 °C to +150 °C junction temperature.

Feature Summary

• Glass passivation provides protection against mechanical stress and ensures stable electrical performance under varying conditions.
• Molding compound meets UL flammability classification 94V-0 for enhanced safety compliance.
• Isolated case design allows for direct mounting to printed circuit boards without additional insulation requirements.

Applications

• General purpose AC to DC full-wave rectification
• Power supply circuits in consumer electronics
• Battery charging systems

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and specific ordering suffixes match project requirements. Review datasheet revisions for any recent parameter updates before finalizing procurement specifications.

Selection Notes

Select this component based on its 6 A current rating and 100 V voltage capability. Ensure thermal management strategies accommodate the specified operating temperature range. Compare physical dimensions of the KBU package against available PCB real estate constraints during the design phase.

Part Context

This part belongs to the KBU series of bridge rectifiers from Vishay. The series includes variants with different voltage ratings such as KBU6A (50 V) and KBU6D (400 V). All share the same KBU package style and general structural characteristics while differing in their reverse voltage specifications.

Replacement Considerations

Direct replacements must maintain identical pinout configuration and current/voltage ratings. Verify that alternative bridge rectifiers support the same glass passivation technology and meet equivalent UL recognition standards for safety compliance.
