2KBP08M-E4/51

Overview

The Vishay General Semiconductor - Diodes Division 2KBP08M-E4/51 is a glass passivated single-phase bridge rectifier designed for general-purpose AC-to-DC full-wave rectification. It features an average forward output rectified current of 2.0 A at 55 °C and a maximum repetitive peak reverse voltage of 800 V. The device supports a peak forward surge current of 60 A and operates within a junction temperature range of -55 to +165 °C. Packaged in the KBPM case style with silver-plated leads, it complies with RoHS 2002/95/EC and WEEE 2002/96/EC directives.

Feature Summary

• Glass passivation provides high surge current capability and high case dielectric strength
• Epoxy formulation meets UL 94V-0 flammability rating
• Terminals are silver plated and solderable per J-STD-002 and JESD22-B102 standards

Applications

• Switching power supplies
• Home appliances
• Office equipment
• Telecommunication applications

Procurement Notes

Verify component authenticity by checking the manufacturer's marking against official datasheet specifications. Confirm compliance status through the supplier's declaration of conformity documents. Ensure storage conditions maintain lead solderability before assembly. Validate that the specific ordering suffix matches the required packaging format for the production line.

Selection Notes

Select this component based on the 800 V reverse voltage requirement and 2 A continuous current capacity. Consider the KBPM package dimensions for printed circuit board layout constraints. Evaluate thermal resistance characteristics relative to the expected ambient operating temperature. Verify compatibility with standard wave or reflow soldering profiles specified in the mechanical data section.

Part Context

This part belongs to the 2KBP series of glass passivated single-phase bridge rectifiers manufactured by Vishay General Semiconductor. The series covers various voltage ratings from 50 V to 1000 V while maintaining a consistent 2 A current rating. The 2KBP08M variant specifically addresses applications requiring 800 V blocking capability within the KBPM plastic encapsulated form factor.

Replacement Considerations

Cross-reference with other manufacturers offering identical electrical parameters and the KBPM package outline. Verify pinout polarity markings match the original design requirements. Ensure replacement components meet the same UL recognition file number E54214 if regulatory compliance is mandatory for the end application.
