GBI15A

Bridge Rectifier Overview

The GBI15A is a single-phase diode bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 15 A and a peak reverse voltage (VRRM) of 50 V. The device operates within a junction temperature range of -50°C to +150°C. Key electrical characteristics include a maximum forward voltage (VF) of 1.1 V at 7.5 A, a leakage current (IR) below 5 µA at 25°C, and a typical reverse recovery time (trr) of 1500 ns. Peak forward surge current ratings are 200 A for 50 Hz and 220 A for 60 Hz half-sine waves.

Bridge Rectifier Feature Summary

• Single-phase bridge rectifier configuration designed for standard commercial and industrial applications.
• Capable of handling high surge currents with specific protective resistance requirements for capacitive loads.
• Utilizes a through-hole GBI-4 package suitable for solder pin mounting.

Bridge Rectifier Applications

• General-purpose AC to DC conversion in industrial power supplies.
• Battery charging circuits requiring robust surge current tolerance.
• Standard commercial electronic equipment operating within specified thermal limits.

Bridge Rectifier Procurement Notes

Verify the specific part number suffix against official Diotec documentation to confirm the exact reverse voltage rating, as the GBI15 series encompasses multiple voltage variants. Ensure that the procurement source provides valid RoHS compliance data and confirms the component is Pb-free and Halogen-free according to the manufacturer's specifications.

Bridge Rectifier Selection Notes

Select this component based on the required 15 A continuous current and 50 V blocking voltage. Designers must account for the thermal resistance values (RthA and RthC) when calculating heat dissipation. For capacitive load applications, calculate the necessary protective resistance (Rt) to prevent exceeding the peak surge current rating during initial charging cycles.

Bridge Rectifier Part Context

The GBI15A belongs to the GBI series of single-phase bridge rectifiers from Diotec Semiconductor. This series includes various voltage ratings ranging from 50 V to 1000 V, sharing common physical dimensions and thermal characteristics while differing in peak reverse voltage capabilities. The GBI package is a standard through-hole form factor widely used in general-purpose rectification tasks.

Bridge Rectifier Replacement Considerations

Compatible substitutes include other single-phase bridge rectifiers with equal or higher current ratings (≥15 A) and voltage ratings (≥50 V). Verify that replacement components match the GBI-4 footprint and maintain similar thermal resistance and surge current specifications to ensure circuit compatibility.
