KBP08M-E4/45

Overview

The KBP08M-E4/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an 800 V maximum repetitive peak reverse voltage and an average forward rectified current of 1.5 A. The device utilizes glass passivation for junction protection and is housed in a surface-mount KBP package. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 50 A at 60 Hz, a typical forward voltage drop of 1 V at 1.5 A, and a maximum reverse leakage current of 5 µA at 800 V. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated junctions provide high reliability and stable performance under varying thermal conditions.
• Designed for efficient AC-to-DC full-wave rectification in compact printed circuit board layouts.
• Capable of withstanding high surge currents during transient load events.

Applications

• General purpose AC-to-DC bridge full wave rectification
• Switching power supply input stages
• Home appliance control circuits

Procurement Notes

Verify the specific suffix E4/45 against official Vishay documentation to confirm lead-free compliance and tape-and-reel packaging specifications. Ensure the ordering part number matches the required voltage and current ratings for the target application before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount solution is required for low-power rectification applications. The KBP package offers a balance between current handling capability and PCB space efficiency. Confirm that the 1.5 A continuous current rating meets the steady-state load requirements and that the 800 V rating provides sufficient margin for the peak inverse voltage in the circuit design.

Part Context

This component belongs to the KBP series of glass passivated single-phase bridge rectifiers from Vishay. The series is engineered for general-purpose use in various electronic equipment where reliable rectification and compact form factors are essential. The KBP08M variant specifically addresses applications requiring 800 V blocking capability.

Replacement Considerations

Compatible substitutes include other Vishay KBP series parts such as KBP08G or KBP08K, provided the voltage and current ratings align with system requirements. Cross-reference with equivalent offerings from manufacturers like Littelfuse or ON Semiconductor, ensuring identical pinout and package dimensions for direct replacement.
