G5SBA20-E3/45

Bridge Rectifier Overview

The G5SBA20-E3/45 is a glass passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor. It features an in-line circuit configuration housed in a GBU case style. The device supports a maximum repetitive peak reverse voltage of 200 V and delivers a maximum average forward rectified output current of 6.0 A at a case temperature of 100 °C. Electrical characteristics include a maximum instantaneous forward voltage of 1.05 V at 3.0 A and a maximum DC reverse current of 5.0 μA at 25 °C. The component withstands a peak forward surge current of 150 A and operates within a junction and storage temperature range of -55 to +150 °C.

Bridge Rectifier Feature Summary

• Glass passivation provides high reliability and stability for general-purpose applications.
• High surge current capability ensures robustness against transient electrical loads.
• High case dielectric strength of 1500 V RMS enhances safety and isolation.
• Molding compound meets UL 94 V-0 flammability rating for improved fire resistance.

Bridge Rectifier Applications

• AC/DC bridge full wave rectification
• Switching mode power supplies
• Monitor and TV circuits
• Printer power systems
• Home appliances

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix to confirm compliance requirements. The E3 suffix indicates RoHS compliance and commercial grade material categorization, while M3 denotes halogen-free status. Confirm package codes such as 45 for tube delivery or 51 for paper tray options when sourcing. Ensure technical parameters align with application thermal and voltage constraints before procurement.

Bridge Rectifier Selection Notes

Select this component based on the required reverse voltage rating and forward current capacity. The G5SBA20 variant is suitable for circuits requiring up to 200 V blocking voltage. Evaluate thermal management needs, as the average forward current derates significantly above 25 °C ambient temperature. Verify that the GBU through-hole package fits the printed circuit board layout and mounting torque specifications.

Bridge Rectifier Part Context

This part belongs to the G5SBA series of glass passivated single-phase bridge rectifiers from Vishay. The series includes variants with different voltage ratings, specifically the G5SBA60 for 600 V and G5SBA80 for 800 V applications. All models share the same GBU case style and similar electrical characteristics regarding surge current and leakage.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same family include G5SBA60-E3/45 and G5SBA80-E3/45. These alternatives offer higher voltage ratings of 600 V and 800 V respectively, while maintaining identical current handling and package dimensions. Cross-brand replacements require verification of pinout compatibility and thermal resistance values.
