MCO75-16IO1

Overview

The MCO75-16IO1 is a single thyristor module manufactured by IXYS, designed for high-current power control applications. It features a peak repetitive reverse voltage of 1600 V and an average on-state current rating of 121 A. The device supports a surge current capacity of 200 A and utilizes a SOT-227B (miniBLOC) chassis mount package with four terminals. Key electrical parameters include a maximum gate trigger current of 200 mA and a peak on-state voltage of 1.35 V. Operating temperatures range from -40°C to +150°C.

Feature Summary

• Single-chip silicon thyristor construction for robust high-power switching
• Chassis mounting design in a compact SOT-227B miniBLOC package
• High thermal stability supporting extended operating temperature ranges

Applications

• Industrial motor drive systems
• Resistive load control circuits
• Power supply rectification modules

Procurement Notes

Verify the specific datasheet version to confirm exact thermal resistance values and mechanical dimensions before integration. Ensure the mounting surface preparation meets the manufacturer's requirements for optimal heat dissipation. Cross-reference terminal configurations to guarantee compatibility with existing busbar or screw connections in the target assembly design.

Selection Notes

Select this component when a single-phase high-voltage thyristor solution is required for chassis-mounted applications. The 1600 V rating suits medium-voltage industrial environments. Compare the 121 A continuous current capability against system load profiles to ensure adequate derating margins under varying thermal conditions and duty cycles.

Part Context

This part belongs to the IXYS MCO series of discrete thyristor modules. These components are engineered for demanding power electronics applications requiring reliable phase control or rectification. The miniBLOC form factor allows for efficient integration into larger power assemblies while maintaining standardized mounting interfaces common in industrial equipment manufacturing.

Replacement Considerations

Potential substitutes include the MCO150-16IO1 for higher current requirements or the MCC312-16IO1 for dual-module configurations. Verify that alternative parts match the 1600 V blocking voltage and compatible package footprint to maintain mechanical and electrical interface integrity without redesigning the host circuit board.
