GBI25B

Bridge Rectifier Overview

The Diotec Semiconductor GBI25B is a single-phase diode bridge rectifier featuring four internal diodes in a bridge configuration. It provides a repetitive peak reverse voltage (VRRM) of 100 V and supports a maximum rectified output current of 4.2 A free-standing at TA = 50°C, or 25 A with forced cooling at TC = 80°C. The device exhibits a typical forward voltage of 0.92 V at 12.5 A and a leakage current below 5 µA at 25°C. It operates within a junction temperature range of -50°C to +150°C and withstands a peak forward surge current of 300 A at 50 Hz.

Bridge Rectifier Feature Summary

• Four diodes integrated in a bridge configuration for efficient AC-to-DC conversion
• UL recognized component ensuring compliance with safety standards
• Capable of free-standing mounting or assembly on heatsinks for thermal management
• Compliant with RoHS directives and REACH regulations

Bridge Rectifier Applications

• 50/60 Hz mains rectification
• General-purpose power supplies
• Commercial and industrial grade equipment

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix when purchasing. Standard units are packed in cardboard trays. Units with the -T suffix are available upon request and are packed in tubes. Confirm that the selected part matches the required voltage rating and packaging format before finalizing orders.

Bridge Rectifier Selection Notes

Select the GBI25B for applications requiring a 100 V reverse voltage rating. Ensure adequate thermal management is provided if operating near the 25 A limit; derating is necessary for free-standing operation above 4.2 A. Verify lead placement maintains ambient temperature conditions as specified in the datasheet for accurate current ratings.

Bridge Rectifier Part Context

The GBI25B belongs to the GBI25 series of single-phase bridge rectifiers from Diotec Semiconductor. This family includes variants with different voltage ratings, such as the GBI25A (50 V) and GBI25J (600 V). All models share the same GBI package outline and general electrical characteristics, differing primarily in their peak reverse voltage capabilities.

Bridge Rectifier Replacement Considerations

Cross-reference with other single-phase bridge rectifiers offering 100 V VRRM and similar current handling. Ensure the replacement component matches the GBI package dimensions and pinout configuration for direct PCB compatibility.
