2KBP08M/1

Overview

The Vishay General Semiconductor - Diodes Division 2KBP08M/1 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. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V per diode and a maximum DC reverse current of 5 µA at 25 °C. The component utilizes the KBPM case style with silver-plated leads.

Feature Summary

• Glass passivation provides high reliability and environmental protection for the junction.
• High surge current capability ensures robustness against transient electrical loads.
• High case dielectric strength enhances safety and isolation in circuit applications.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type, such as tube or tray configurations, and compliance status like RoHS directives. Confirm lead finish specifications, particularly if E4 suffixes are required for consumer grade applications. Ensure the selected variant matches the exact voltage rating and thermal requirements for the target design.

Selection Notes

Select this component based on the 800 V reverse voltage requirement and 2 A continuous current capacity. Evaluate thermal management needs, considering the specified thermal resistance values and derating curves for ambient temperatures above 55 °C. Verify that the PCB footprint accommodates the KBPM package dimensions and terminal spacing for proper mounting and soldering.

Part Context

This part belongs to the 2KBP series of glass-passivated single-phase bridge rectifiers from Vishay. The series covers various voltage ratings from 50 V to 1000 V while maintaining a consistent 2 A current rating and KBPM package form factor. It serves as a standard solution for low-power rectification tasks requiring reliable performance in compact designs.

Replacement Considerations

Compatible substitutes within the same Vishay family include the 3N258 model, which shares identical electrical parameters and pinout configuration. Cross-referencing with other manufacturers requires verifying matching voltage, current, and thermal specifications alongside physical package compatibility.
