2KBP005M-E4/45

Overview

The Vishay General Semiconductor - Diodes Division 2KBP005M-E4/45 is a glass passivated single-phase bridge rectifier in the KBPM case style. It features a maximum repetitive peak reverse voltage (VRRM) of 50 V and a maximum average forward output rectified current (IF(AV)) of 2.0 A at an ambient temperature of 55 °C. The device supports a peak forward surge current (IFSM) of 60 A for a single half-sine wave superimposed on rated load. Electrical characteristics include a maximum instantaneous forward voltage drop (VF) of 1.1 V at 3.14 A and a maximum DC reverse current (IR) of 5 µA at 25 °C. The component operates within a junction and storage temperature range of -55 to +165 °C.

Feature Summary

• Glass passivation provides high case dielectric strength and reliability for printed circuit board mounting.
• Silver plated leads ensure solderability per J-STD-002 and JESD22-B102 standards.
• Epoxy formulation meets UL 94V-0 flammability rating requirements.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation, as it determines the delivery mode and base quantity. The /45 suffix indicates tube packaging with a base quantity of 30 units. Confirm RoHS compliance status and lead plating specifications (E4 suffix denotes silver-plated consumer grade terminals) prior to procurement to ensure alignment with assembly requirements.

Selection Notes

Select this component when a 50 V peak reverse voltage rating and 2 A continuous forward current are required in a compact through-hole package. Ensure the application environment remains within the specified -55 °C to +165 °C operating temperature range. Consider the thermal resistance values (RθJA of 30 °C/W and RθJL of 11 °C/W) for heat dissipation planning on the PCB layout.

Part Context

This part belongs to the 2KBP005M thru 2KBP10M series, which offers varying voltage ratings from 50 V to 1000 V while maintaining a consistent 2 A current capacity and KBPM package footprint. The series shares identical mechanical dimensions and electrical characteristics regarding current handling and surge capability, differing primarily in the maximum repetitive peak reverse voltage specification.

Replacement Considerations

Cross-reference with other Vishay parts in the same series such as 2KBP01M or 2KBP02M if higher voltage ratings are needed. Verify that alternative manufacturers offer equivalent KBPM package dimensions and matching IF(AV) and VRRM specifications to ensure mechanical and electrical compatibility.
