GBI25G

Bridge Rectifier Overview

The Diotec Semiconductor GBI25G is a single-phase diode bridge rectifier designed for commercial and industrial applications. It features four internal diodes in a bridge configuration with a repetitive peak reverse voltage (VRRM) of 400 V and a maximum alternating input voltage of 280 V. The device supports a maximum rectified output current of 25 A on a heatsink at 80°C case temperature, or 4.2 A free-standing at 50°C ambient temperature. Key electrical characteristics include a typical forward voltage of 0.92 V at 12.5 A, a peak forward surge current of 300 A at 50 Hz, and a reverse leakage current below 5 µA at 25°C.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix when sourcing this component. Standard versions are packed in cardboard trays, while tube packaging requires the -T suffix. Confirm compliance requirements such as REACH and conflict minerals status directly with the manufacturer or authorized distributors before finalizing procurement plans.

Bridge Rectifier Selection Notes

Select the GBI25G for circuits requiring a 400 V blocking voltage and up to 25 A continuous current with adequate thermal management. Ensure the design accounts for the recommended protective resistance and load capacitor values to prevent exceeding the 300 A surge current rating during startup or fault conditions.

Bridge Rectifier Part Context

This component belongs to the GBI series of single-phase bridge rectifiers from Diotec Semiconductor. The series spans multiple voltage ratings from 50 V to 1000 V, sharing common mechanical dimensions and thermal characteristics. The GBI25G specifically targets mid-range voltage applications within this standardized product family.

Bridge Rectifier Replacement Considerations

Cross-reference with other GBI25xx models if voltage ratings differ. Verify that alternative bridge rectifiers match the 25 A current capacity, DO-201AB-like package dimensions, and thermal resistance specifications to ensure direct compatibility in existing designs.
