3KBP02M-E4/51

Bridge Rectifier Overview

The Vishay General Semiconductor - Diodes Division 3KBP02M-E4/51 is a glass passivated single-phase bridge rectifier designed for general-purpose AC-to-DC full-wave rectification. It features a maximum average forward output rectified current of 3.0 A at an ambient temperature of 55 °C and supports a maximum repetitive peak reverse voltage of 200 V. The device exhibits a maximum instantaneous forward voltage drop of 1.05 V at rated current and a peak forward surge current capability of 80 A. Operating junction temperatures range from -55 °C to +150 °C, with typical thermal resistance values of 30 °C/W (junction-to-ambient) and 11 °C/W (junction-to-lead).

Bridge Rectifier Feature Summary

• Glass-passivated junction construction provides high reliability and low leakage current.
• High surge current capability suitable for demanding power supply applications.
• Silver-plated leads ensure solderability per J-STD-002 and JESD22-B102 standards.

Bridge Rectifier Applications

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

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. The E4 suffix indicates consumer grade specifications with silver-plated terminals. Confirm that the delivery mode matches project requirements, as standard packaging may vary between tubes and anti-static PVC trays depending on the base quantity selected.

Bridge Rectifier Selection Notes

Select this component when a 3 A continuous current rating and 200 V reverse blocking voltage are required. Ensure the application operates within the specified -55 °C to +150 °C junction temperature range. Consider the KBPM case style for through-hole mounting on printed circuit boards where high dielectric strength and UL recognition are necessary design factors.

Bridge Rectifier Part Context

This part belongs to the 3KBP series of glass passivated single-phase bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants ranging from 50 V to 800 V reverse voltage ratings while maintaining a consistent 3 A average forward current capacity. The KBPM case style is standardized across the family for uniform mechanical integration.

Bridge Rectifier Replacement Considerations

Direct substitutes include other Vishay 3KBP series parts such as 3KBP04M or 3KBP06M if higher voltage ratings are acceptable. Verify that alternative manufacturers' bridge rectifiers match the 3 A current, 200 V reverse voltage, and KBPM package dimensions.
