2KBP01M-E4/45

Overview

The Vishay General Semiconductor - Diodes Division 2KBP01M-E4/45 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 100 V. The device supports a peak forward surge current of 60 A and operates within a junction temperature range of -55 °C to +165 °C. 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 rated blocking voltage. The component utilizes a KBPM case style with silver-plated leads.

Feature Summary

• Glass passivation provides mechanical strength and protection against soldering tools and chemical solvents
• High surge current capability ensures reliability during transient load conditions
• Epoxy casing meets UL 94V-0 flammability rating for enhanced safety

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm package quantity and delivery mode, as variations exist between tube and tray formats. Confirm RoHS compliance status and lead plating specifications (silver) prior to integration. Ensure thermal management aligns with the specified ambient temperature derating curves for optimal performance.

Selection Notes

Select this component when a 2 A continuous current rating and 100 V reverse voltage are required in a compact KBPM footprint. Evaluate thermal resistance values relative to PCB copper pad dimensions for heat dissipation. Consider the operating junction temperature limit of 165 °C for high-temperature environments compared to standard 150 °C alternatives.

Part Context

This part belongs to the 2KBP series of glass-passivated bridge rectifiers manufactured by Vishay General Semiconductor. The series covers various voltage ratings from 50 V to 1000 V while maintaining a consistent 2 A current capacity and KBPM package style. The E4 suffix indicates consumer-grade composition with lead-free terminals compliant with environmental directives.

Replacement Considerations

Cross-reference other parts within the 2KBP series or equivalent KBPM packages from other manufacturers that match the 2 A current and 100 V voltage ratings. Verify pinout compatibility and thermal resistance specifications before substitution.
