GSXD120A004S1-D3

Overview

The GSXD120A004S1-D3 is a Silicon Carbide (SiC) Schottky diode module manufactured by SemiQ. It features a 45V reverse voltage rating and supports an average rectified forward current of 120A per diode. The component utilizes a SOT-227-4 package, also known as miniBLOC, designed for screw mounting. This configuration provides robust thermal performance suitable for high-power applications requiring low forward voltage drop and high efficiency.

Feature Summary

• Utilizes Silicon Carbide technology for superior thermal stability and switching performance compared to traditional silicon devices
• Features a Schottky barrier structure to minimize forward voltage drop and reduce conduction losses
• Designed with a rugged SOT-227-4 mechanical housing to facilitate secure screw-mount installation and efficient heat dissipation

Applications

• High-efficiency DC-DC converters
• Industrial power supply units
• Uninterruptible power supply (UPS) systems

Procurement Notes

Verify the specific datasheet version provided by the supplier to ensure alignment with the latest electrical characteristics and mechanical dimensions. Confirm that the ordering suffix matches the required pinout and packaging specifications. Request manufacturer certification or traceability documents to validate authenticity and origin. Ensure storage conditions comply with moisture sensitivity levels if applicable prior to assembly.

Selection Notes

Select this component when designing circuits requiring low forward voltage loss at high currents. The 45V rating limits suitability to low-voltage output stages. Evaluate thermal management requirements based on the 120A current capacity and the thermal resistance inherent to the SOT-227 package. Ensure gate drive or control logic compatibility with the intended system architecture.

Part Context

This part belongs to the GSXD series of SiC Schottky diodes from SemiQ. The series offers various current ratings and voltage options within the same mechanical footprint family. The GSXD120 variant specifically targets applications needing higher current handling than lower-rated siblings while maintaining the compact miniBLOC form factor.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching electrical parameters such as 45V reverse voltage, 120A forward current, and SOT-227-4 package dimensions.
