• Designed for high-temperature operation with a maximum junction temperature capability up to 175°C.

Applications

• High-frequency switching power supplies
• Industrial motor drives and inverters
• Uninterruptible Power Supply (UPS) systems

Procurement Notes

Verify the specific suffix D3 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS compliance status. Ensure that the SOT-227-4 mounting torque specifications are strictly followed during assembly to prevent mechanical stress on the module. Cross-reference the 180V rating with system voltage requirements to avoid overvoltage conditions. Confirm that the thermal interface material selected matches the required thermal resistance for the intended heat sink application.

Selection Notes

Select this component when a low forward voltage drop and high current handling capacity are required in a compact form factor. The SiC material choice is critical for applications prioritizing reduced switching losses and higher operating temperatures. Compare the 120A continuous current rating against peak load demands to ensure adequate safety margins. Consider the dual configuration benefits for bridge rectifier or synchronous rectification topologies where space constraints limit discrete component usage.

Part Context

This module belongs to the GSXD series of SiC Schottky diodes from SemiQ, targeting high-efficiency power conversion. It complements other modules in the lineup by offering a balance between voltage rating and current capacity in a standardized footprint. The series is engineered to replace conventional silicon fast-recovery diodes in modern power electronics, providing improved energy efficiency and reduced cooling requirements due to lower thermal generation.

Replacement Considerations

Direct substitutes must match the 180V/120A specification and SOT-227-4 package. Verify equivalent forward voltage characteristics to maintain system efficiency. Check if alternative manufacturers offer compatible SiC Schottky diodes with identical thermal and electrical profiles for supply chain resilience.
