KBU8G-M3/P

Overview

The KBU8G-M3/P 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 400 V. The device utilizes glass passivation for the silicon chips, ensuring low leakage currents. Key electrical parameters include a forward voltage (Vf) of 1 V at 8 A and a reverse leakage current (Ir) of 10 µA at 400 V. The component supports a maximum non-repetitive peak forward surge current of 300 A and operates within a junction temperature range of -50°C to +150°C.

Feature Summary

• Glass passivated silicon chips provide stable performance and low leakage characteristics.
• High surge current capability allows robust operation during transient events.
• Isolated flange mount construction facilitates efficient thermal management.

Applications

• General purpose AC to DC conversion in power supplies
• Battery charging circuits requiring high reliability
• Industrial control systems with moderate power demands

Procurement Notes

Verify the specific suffix P indicates tube packaging when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the ordering part number matches the required voltage and current ratings for the target application design.

Selection Notes

Select this component for applications requiring 8 A continuous current and 400 V blocking voltage. Consider the KBU package dimensions for PCB layout constraints. Evaluate thermal dissipation requirements based on the specified operating temperature range and ambient conditions.

Part Context

This component belongs to the KBU series of bridge rectifiers from Vishay. The series offers various voltage ratings and current capacities in a standardized flange-mount package. The M3 suffix typically denotes lead-free and halogen-free compliance according to IEC 60747 standards.

Replacement Considerations

Direct parameter-equivalent substitutes may include other Vishay KBU series variants with matching 8 A and 400 V ratings. Verify pinout compatibility and thermal resistance specifications before substituting with components from different manufacturers.
