GBLA08-E3/51

Overview

The GBLA08-E3/51 is a glass-passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It belongs to the GBL series and utilizes the GBL in-line package. The device features a maximum average forward rectified output current of 4.0 A at a case temperature of 50 °C, with a peak forward surge current capability of 120 A. The maximum repetitive peak reverse voltage (VRRM) for this specific model is 800 V. Electrical characteristics include a typical instantaneous reverse current of 5 μA at rated DC blocking voltage and a maximum instantaneous forward voltage drop of 1.0 V at 4.0 A. The component supports an operating junction and storage temperature range from -55 °C to +150 °C.

Feature Summary

• Glass passivation provides protection against mechanical stress and ensures long-term stability.
• High surge current capability allows handling of transient load conditions.
• Ideal for printed circuit board mounting due to the GBL case design.
• Meets UL recognition standards for safety compliance.

Applications

• AC/DC bridge full wave rectification
• Monitor power supplies
• TV and printer adapters
• SMPS and audio equipment

Procurement Notes

Verify part availability status as the datasheet indicates End of Life status for the GBLAxx series. Confirm that the E3 suffix denotes RoHS compliance and commercial grade material categorization. Ensure ordering codes match the required delivery mode, such as anti-static PVC trays for the /51 suffix. Validate technical specifications against current project requirements before finalizing procurement decisions.

Selection Notes

Select the GBLA08 variant specifically when an 800 V reverse voltage rating is required within the GBL family. Consider the 4 A average forward current limit and thermal resistance values for heat dissipation planning. Evaluate the operating temperature range to ensure suitability for the intended environmental conditions. Compare alternative devices if the EOL status impacts long-term supply chain stability.

Part Context

This component is part of 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 models share similar electrical characteristics regarding current handling and package dimensions, differing primarily in their maximum repetitive peak reverse voltage capabilities.

Replacement Considerations

The official alternative device listed in the datasheet is the GBL08E series. Designers should verify pinout compatibility and thermal performance when transitioning from the GBLA08-E3/51 to the GBL08E equivalent.
