2KBP08M-E4/45

Overview

The Vishay General Semiconductor - Diodes Division 2KBP08M-E4/45 is a glass passivated single-phase bridge rectifier belonging to the 2KBP series. It features a KBPM case style with silver-plated leads and epoxy meeting UL 94V-0 flammability ratings. The component supports a maximum average forward output rectified current of 2.0 A at an ambient temperature of 55 °C, with a peak forward surge current capability of 60 A. It offers a maximum repetitive peak reverse voltage of 800 V and a maximum RMS voltage of 560 V. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V at 3.14 A and a maximum DC reverse current of 5 µA at 25 °C. The device operates within a junction and storage temperature range of -55 °C to +165 °C.

Feature Summary

• Glass passivation provides high surge current capability and high case dielectric strength
• Silver-plated leads ensure solderability per J-STD-002 and JESD22-B102 standards
• Epoxy compound meets UL 94V-0 flammability rating for safety compliance

Applications

• AC-to-DC bridge full wave rectification in switching power supplies
• Rectification circuits for home appliances
• Power conditioning in office equipment
• Telecommunication applications

Procurement Notes

Verify the specific ordering suffix /45 to confirm tube packaging and base quantity requirements. Confirm RoHS compliance status as the E4 suffix indicates consumer grade materials. Validate that the KBPM package dimensions match the target PCB footprint before finalizing procurement orders.

Selection Notes

Select this component when an 800 V peak reverse voltage rating is required alongside a 2 A continuous current capacity. Ensure the application environment allows for operation up to 165 °C junction temperature. Consider the thermal resistance values if mounting on printed circuit boards with limited copper pad areas for heat dissipation.

Part Context

This part belongs to the 2KBP005M through 2KBP10M family, which shares identical mechanical and electrical specifications except for the voltage rating. The 2KBP08M variant specifically targets 800 V applications within this standardized bridge rectifier lineup manufactured by Vishay.

Replacement Considerations

Direct substitutes within the same series include 2KBP08M-E4/51, which differs only in packaging format (tray versus tube). Other voltage variants like 2KBP06M or 2KBP10M may be considered if voltage margins allow.
