GBLA06-E3/51

Overview

The GBLA06-E3/51 is a glass passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an in-line circuit configuration within the GBL package. The device supports a maximum repetitive peak reverse voltage of 600 V and a maximum average forward rectified output current of 4.0 A at a case temperature of 50 °C, or 3.0 A at an ambient temperature of 40 °C. It exhibits a typical instantaneous forward voltage drop of 1.0 V at 4.0 A and a maximum DC reverse current of 5 μA at rated blocking voltage. The unit withstands a peak forward surge current of 120 A and operates within a junction and storage temperature range of -55 to +150 °C.

Feature Summary

• Glass passivation provides mechanical strength and meets UL 94 V-0 flammability ratings for the molding compound.
• High surge current capability ensures robustness against transient electrical loads.
• Terminals are matte tin plated, ensuring solderability per J-STD-002 standards.

Applications

• General purpose AC/DC bridge full wave rectification
• Monitor and TV power supply circuits
• Printer and SMPS adapter designs
• Audio equipment and home appliances

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm compliance with RoHS directives and check for specific packaging requirements such as anti-static PVC trays. Validate that the ordering suffix matches the required delivery mode and base quantity specifications before finalizing procurement orders.

Selection Notes

Select this component based on the 600 V reverse voltage rating and 4.0 A continuous current capacity. Ensure thermal management aligns with the specified derating curves for both heat-sink mounting and PCB configurations. Verify that the operating environment remains within the -55 to +150 °C junction temperature limits for reliable performance.

Part Context

This part belongs to the GBLAxx series of glass passivated single-phase bridge rectifiers. The series includes variants with different voltage ratings ranging from 50 V to 1000 V, all sharing the same GBL package outline and general electrical characteristics. The E3 suffix indicates RoHS compliance and halogen-free status.

Replacement Considerations

The official alternative device listed in the datasheet is the GBL06E series. Designers should verify pinout compatibility and ensure the replacement meets the original 600 V and 4.0 A specifications.
