GBL01/1

Overview

The GBL01/1 is a single-phase silicon bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum average forward output current of 3 A and a repetitive peak reverse voltage rating of 100 V. The device utilizes glass passivated junctions for reliability and is housed in an isolated plastic package with four through-hole terminals. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 158 A and a typical reverse leakage current of less than 0.1 µA. The component is designed for printed circuit board mounting and meets UL recognition standards.

Feature Summary

• Glass passivated junctions provide high reliability under various operating conditions
• Isolated plastic case construction ensures high dielectric strength between terminals and heatsink
• High surge current capability supports robust performance during transient overload events
• Low reverse leakage current minimizes power loss in blocking states

Applications

• Printed circuit board mounted AC to DC conversion circuits
• General purpose rectification in low to medium power supplies
• Battery charging applications requiring isolated bridge configurations

Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet, as variations may exist regarding flammability ratings or terminal plating. Confirm that the procurement source provides original manufacturer documentation rather than third-party interpretations. Ensure compliance with RoHS directives if required by the end application. Cross-reference the part number with official Vishay catalogs to confirm availability status and manufacturing location changes prior to ordering.

Selection Notes

Select this component when a 3 A continuous current rating and 100 V reverse voltage are sufficient for the load requirements. The GBL package form factor is suitable for through-hole PCB assembly where space allows for larger footprints compared to surface mount alternatives. Consider the thermal management capabilities of the isolated case design for heat dissipation needs. Evaluate the 158 A surge rating against potential inrush currents in the target circuit to ensure adequate safety margins.

Part Context

This component belongs to the GBL series of single-phase bridge rectifiers produced by Vishay. The series offers various voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 3 A to 4 A current capacity depending on the specific model variant. The GBL01 represents the lowest voltage option within this specific current class, providing a standardized solution for low-voltage rectification tasks in industrial and consumer electronics.

Replacement Considerations

Direct replacements must match the 3 A current rating, 100 V reverse voltage, and GBL package outline. Verify terminal pinout compatibility to ensure correct AC input and DC output connections. Check for equivalent surge current ratings and thermal resistance values to maintain circuit performance integrity.
