KBP08M-9E4/51

Overview

The KBP08M-9E4/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an average forward rectified current (Io) of 1.5 A and a maximum repetitive peak reverse voltage (Vrrm) of 800 V. The device utilizes glass-passivated silicon junctions for enhanced reliability. Key electrical characteristics include a typical forward voltage drop of 1.3 V at 1.57 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 and is housed in a through-hole KBPM package.

Feature Summary

• Glass-passivated junctions provide high reliability and protection against mechanical stress
• High surge current capability suitable for demanding power applications
• Compliant with RoHS 2002/95/EC and WEEE 2002/96/EC directives

Applications

• AC-to-DC bridge full-wave rectification in switching power supplies
• General-purpose rectification in home appliances
• Industrial control systems requiring robust diode protection

Procurement Notes

Verify the specific suffix '9E4' corresponds to the required lead-free and halogen-free configuration as per Vishay's official documentation. Confirm that the KBPM package style matches the target PCB footprint requirements. Ensure the 800 V rating aligns with the peak inverse voltage demands of the specific circuit design before finalizing procurement.

Selection Notes

Select this component when an 800 V blocking voltage and 1.5 A continuous current are required in a compact through-hole format. The KBPM case offers high dielectric strength compared to smaller packages. Consider the thermal management implications of the 1.3 V forward voltage drop at rated load conditions during system design.

Part Context

This part belongs to the KBP series of single-phase bridge rectifiers from Vishay. The series is characterized by glass passivation and is designed for general-purpose use. The KBP08M variant specifically denotes the 800 V rating within this family, sharing common packaging and feature sets with other ratings like KBP06 or KBP10.

Replacement Considerations

Direct replacements must match the 1.5 A current, 800 V voltage, and KBPM through-hole package. Verify pinout compatibility and thermal characteristics. Other manufacturers offering equivalent glass-passivated bridge rectifiers in the KBPM form factor may serve as alternatives if electrical parameters are identical.
