GBL005

Overview

The Taiwan Semiconductor GBL005 is a single-phase bridge rectifier within the GBL series, rated for a maximum average forward current of 4 A and a repetitive peak reverse voltage of 50 V. It utilizes glass passivated chip junctions to achieve low leakage currents, typically less than 0.1 μA at room temperature. The device operates with a junction temperature range from -55 °C to +150 °C and withstands surge peak forward currents up to 150 A. Electrical characteristics include a maximum forward voltage of 1.1 V at 4 A and a typical junction-to-ambient thermal resistance of 32 °C/W.

Feature Summary

• Glass passivated chip junctions ensure high reliability and low reverse leakage current.
• Molding compound meets UL 94V-0 flammability rating for safety compliance.
• Matte tin plated leads are solderable per J-STD-002 standards.

Applications

• Switching mode power supplies (SMPS)
• Power adapters
• Lighting applications

Procurement Notes

Verify the specific ordering code suffix when purchasing. The standard package designation is GBLx, while the 'H' suffix indicates AEC-Q101 automotive qualification. Confirm that the component matches the required voltage rating and packaging format before integration into production systems.

Selection Notes

Select the GBL005 specifically for circuits requiring a 50 V reverse voltage rating. Higher voltage variants in the series, such as GBL01 or GBL02, offer increased blocking capabilities but may not be necessary for lower voltage designs. Ensure the thermal management design accounts for the specified junction-to-ambient resistance under expected load conditions.

Part Context

This component belongs to the GBL series of standard bridge rectifiers manufactured by Taiwan Semiconductor. The series covers a wide voltage range from 50 V to 1000 V, sharing common mechanical dimensions and features like the GBL case style. The GBL005 represents the lowest voltage option in this specific lineup.

Replacement Considerations

Direct substitutes must match the 4 A current rating, 50 V reverse voltage, and GBL package footprint. Verify that alternative components meet the same thermal and electrical specifications for seamless replacement.

FAQ

Is the GBL005 qualified for automotive applications?

Standard versions are not explicitly listed as automotive qualified. Only the variant with the 'H' suffix (GBL005H) is designated as AEC-Q101 qualified.

What is the maximum non-repetitive forward surge current?

The device can withstand a surge peak forward current of 150 A for an 8.3 ms single half sine-wave superimposed on the rated load.

How is polarity indicated on the device?

Polarity is marked directly on the body of the component, following the standard marking diagram provided in the datasheet.
