2KBP005M-E4/51

Overview

The Vishay 2KBP005M-E4/51 is a glass passivated single-phase bridge rectifier in the KBPM case style. It provides a maximum average forward output rectified current of 2.0 A at an ambient temperature of 55 °C and supports a peak forward surge current of 60 A for half-sine waves under rated load conditions. The device features a maximum repetitive peak reverse voltage of 50 V, with corresponding RMS and DC blocking voltages of 35 V and 50 V respectively. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V per diode at 3.14 A and a maximum DC reverse current of 5 µA at 25 °C. Thermal resistance values are specified as 30 °C/W from junction to ambient and 11 °C/W from junction to lead.

Feature Summary

• Glass passivation ensures high reliability and stability in general-purpose rectification applications
• High surge current capability allows handling of transient loads effectively
• Epoxy casing meets UL 94V-0 flammability rating for safety compliance
• Silver plated leads provide solderability compatible with standard manufacturing processes

Applications

• AC-to-DC bridge full wave rectification for switching power supplies
• Power circuits within home appliances
• Rectification stages in office equipment
• Telecommunication system power modules

Procurement Notes

Verify component authenticity by checking the manufacturer's marking against official datasheet specifications. Confirm that the E4 suffix indicates consumer grade silver-plated terminals and that the /51 suffix corresponds to anti-static PVC tray packaging containing 600 units. Ensure RoHS compliance documentation aligns with Directive 2011/65/EU requirements before finalizing procurement orders.

Selection Notes

Select this component when a 2 A continuous current rating and 50 V reverse voltage withstand capability are required for through-hole PCB mounting. Consider the KBPM package dimensions and thermal resistance characteristics if operating near the maximum junction temperature limit of 165 °C. Evaluate the 60 A surge current capacity against potential startup transients in the specific circuit design to ensure adequate safety margins.

Part Context

This part belongs to the Vishay 2KBP series of glass passivated single-phase bridge rectifiers, which share the KBPM case style. The series spans various voltage ratings from 50 V to 1000 V, including variants like the 2KBP01M through 2KBP10M. These components are designed for general purpose use and offer consistent electrical characteristics across the family while differing primarily in their peak reverse voltage ratings.

Replacement Considerations

Direct substitutes within the same series include the 2KBP01M-E4/51 (100 V), 2KBP02M-E4/51 (200 V), and other higher voltage variants sharing the identical 2 A current rating and KBPM package. Cross-referencing with equivalent generic bridge rectifiers requires verifying matching current, voltage, and thermal specifications.
