2KBP04M/1

Overview

The 2KBP04M/1 is a glass-passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a peak reverse voltage of 400 V and an average rectified forward current of 2 A. The device utilizes standard technology and is housed in a KBPM plastic package with four pins. It is designed for surface-mount applications and supports a junction temperature range up to 150°C.

Feature Summary

• Glass passivation protects the junctions against mechanical stress
• Plastic package meets UL flammability classification 94V-0
• Designed for high reliability in general-purpose rectification

Applications

• AC to DC power supply circuits
• Battery charging systems
• General-purpose rectification in electronic equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the obsolete status does not impact long-term supply requirements. Request original datasheets and test reports to ensure compliance with specified electrical parameters before integration into production designs.

Selection Notes

Select this component when a 400 V, 2 A single-phase bridge rectifier is required for surface-mount assembly. Ensure the design accommodates the thermal characteristics of the KBPM package. Consider alternative active parts if lead time or availability constraints exist due to the obsolete status.

Part Context

This part belongs to the 2KBP series of glass-passivated bridge rectifiers from Vishay. The series offers various voltage ratings ranging from 50 V to 1000 V with a consistent 2 A current rating. The 2KBP04M/1 specifically addresses the 400 V requirement within this family, providing a standardized solution for medium-voltage rectification tasks.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the 2KBP04M/1 is marked as obsolete, engineers should consult Vishay's official replacement guides or select equivalent active components with matching 400 V, 2 A specifications and compatible pinout configurations.
