GBU402 D2G

Overview

The GBU402 D2G is a single-phase standard bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a maximum repetitive peak reverse voltage of 100 V and an average rectified output current of 4 A. The forward voltage drop is specified at 1.1 V when conducting 4 A, with a maximum reverse leakage current of 5 µA at 100 V. The device operates within a junction temperature range of -55°C to 150°C and utilizes a GBU through-hole package.

Feature Summary

• Glass passivated junction construction for enhanced reliability
• Molded plastic case with UL flammability classification 94V-0
• Terminals are pure tin plated and lead-free, compliant with MIL-STD-208 solderability standards

Applications

• Printed circuit board mounting in power supply circuits
• General purpose AC to DC conversion
• Low voltage rectification applications requiring high surge overload rating

Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm that the specific suffix corresponds to the intended packaging and marking requirements. Check manufacturer documentation for any updates regarding material declarations or environmental compliance status prior to final procurement decisions.

Selection Notes

Select this component for designs requiring a 100 V blocking capability with 4 A continuous current handling. Ensure the thermal management strategy supports the specified 150°C maximum junction temperature. Verify that the GBU footprint matches the PCB layout constraints and that the through-hole mounting torque limits are respected during assembly.

Part Context

This part belongs to the GBU series of single-phase bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings ranging from 200 V to 1000 V while maintaining a consistent 4 A current capacity and GBU package form factor for standardized mechanical integration across different power supply designs.

Replacement Considerations

Direct substitutes include other GBU402 variants from different manufacturers such as MCC GBU402-BP. Ensure replacement parts match the 100 V reverse voltage, 4 A current rating, and GBU package dimensions for pin-compatible installation.
