KBU8A-E4/51

Overview

The KBU8A-E4/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an average forward rectified current (Io) of 8 A and a maximum repetitive peak reverse voltage (Vrrm) of 50 V. The device utilizes standard silicon technology with a forward voltage (Vf) of 980 mV at 8 A and a reverse leakage current of 10 µA at 50 V. Designed for through-hole mounting in the KBU package, it operates within a junction temperature range of -50°C to 150°C.

Feature Summary

• Single-phase bridge rectification using standard silicon technology
• Through-hole installation in a compact KBU plastic package
• High thermal stability supporting junction temperatures up to 150°C

Applications

• General-purpose AC to DC power supply conversion
• Low-voltage rectification in consumer electronics
• Industrial control circuit power stages

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm lead times and packaging configurations. Confirm RoHS compliance status via the manufacturer datasheet. Ensure the ordering part number matches the required voltage and current ratings for the target application design.

Selection Notes

Select this component when a low-voltage, high-current single-phase rectifier is required. The KBU package offers robust mechanical stability for through-hole PCBs. Compare Vf characteristics against alternative packages like GBU if space constraints differ. Verify thermal management requirements for continuous 8 A operation.
