GBL01

Overview

The GBL01 is a single-phase silicon bridge rectifier from the Taiwan Semiconductor GBL series, rated for a maximum average forward current of 4 A at a case temperature of 50°C and 3 A at an ambient temperature of 40°C. It features a repetitive peak reverse voltage (VRRM) of 100 V with a corresponding RMS voltage of 70 V. The device supports a surge peak forward current of 150 A for an 8.3 ms half-sine wave. Electrical characteristics include a typical forward voltage of 1.0 V at 2 A and 1.1 V at 4 A, alongside a maximum reverse current of 5 µA at 25°C. The junction-to-ambient thermal resistance is 32 °C/W.

Feature Summary

• Glass passivated chip junctions provide reliable operation and low leakage current.
• Molded plastic case meets UL 94V-0 flammability rating for safety compliance.
• Matte tin plated leads ensure solderability per J-STD-002 standards.

Applications

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

Procurement Notes

Verify the specific ordering code to confirm the exact voltage rating and packaging format. Standard tubes contain 25 units. Check for the 'H' suffix if automotive-grade AEC-Q101 qualification is required for the application environment. Confirm RoHS and halogen-free status based on the final part number designation before placing orders.

Selection Notes

Select the GBL01 when a 100 V blocking capability is necessary for AC-to-DC conversion circuits. Ensure the operating ambient temperature allows for a 3 A continuous load or utilize heatsinking to maintain the 4 A rating at higher case temperatures. Verify that the 150 A surge rating accommodates inrush currents within the system design parameters.

Part Context

This component belongs to the GBL005 through GBL10 family of standard bridge rectifiers manufactured by Taiwan Semiconductor. The series offers varying reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 4 A forward current capacity and GBL package outline. The GBL01 specifically addresses mid-range voltage requirements within this standardized product line.

Replacement Considerations

Cross-reference with other manufacturers offering the GBL package outline and 100 V / 4 A specifications. Ensure equivalent thermal resistance and surge current capabilities are met. Verify that any substitute component also utilizes glass passivation and meets the same mechanical mounting dimensions.

FAQ

Is the GBL01 qualified for automotive applications?

Standard versions are not explicitly qualified for automotive use. However, the GBL series offers an AEC-Q101 qualified option, indicated by the 'H' suffix in the ordering code (e.g., GBL01H).

What is the maximum junction temperature for this device?

The maximum operating junction temperature (TJ MAX) is 150°C, as specified in the absolute maximum ratings table.

How does the forward current rating change with temperature?

The device is rated for 4 A at a case temperature of 50°C. At an ambient temperature of 40°C, the maximum average forward rectified output current is derated to 3 A.
