GBI20B

Bridge Rectifier Overview

The GBI20B is a single-phase bridge rectifier manufactured by Diotec Semiconductor, designed for commercial and industrial applications. It features a repetitive peak reverse voltage (VRRM) of 100 V and supports a maximum rectified output current of 20 A at a case temperature of 100°C. The device exhibits a forward voltage drop below 1.1 V at 10 A and handles a peak forward surge current of 220 A at 50 Hz. Operating within a junction temperature range of -50°C to +150°C, it utilizes a GBI-4 through-hole package with solder pin termination.

Bridge Rectifier Feature Summary

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix when purchasing. Standard versions are designated as commercial grade. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes qualification status. Confirm these designations against official documentation to ensure the correct reliability grade is obtained for the intended application environment.

Bridge Rectifier Selection Notes

Select this component based on the required reverse voltage rating and thermal management strategy. The rated current decreases significantly if operating without forced cooling; verify the load capacitor and protective resistance values to manage surge currents effectively. Ensure the mounting torque adheres to the specified mechanical limits for the M3 terminals.

Bridge Rectifier Part Context

This part belongs to the GBI series of single-phase bridge rectifiers from Diotec Semiconductor. The series spans various voltage ratings from 50 V to 1000 V, sharing common physical dimensions and thermal characteristics. The GBI20B specifically addresses lower voltage AC-to-DC conversion requirements within this standardized product family.

Bridge Rectifier Replacement Considerations

Cross-reference with other GBI-series variants like GBI20A or GBI20D only if the circuit voltage allows. Verify that any substitute maintains the same 20 A current rating and compatible package footprint to ensure mechanical fit and electrical performance alignment.
