MCC94-20IO1B

Overview

The MCC94-20IO1B is a silicon thyristor module manufactured by IXYS, belonging to the MCC94 series. It features a phase leg configuration housed in a TO-240AA package with screw mount installation style. The device supports an output current of 94 A and withstands a reverse voltage of 2.2 kV. Key electrical parameters include a forward voltage of 1.46 V, a gate trigger current of 150 mA, and a maximum holding current of 150 mA. The operational temperature range spans from -40 C to +125 C, and the unit weighs approximately 90 g.

Feature Summary

• High-voltage capability with 2.2 kV reverse voltage rating for robust power handling
• Phase leg topology designed for efficient integration into controlled rectifier circuits
• Wide thermal operating range ensuring stability across extreme environmental conditions

Applications

• Industrial motor drives requiring high-power phase control
• Static VAR compensators for power factor correction
• High-voltage DC transmission systems

Procurement Notes

Verify the specific part number MCC94-20IO1B against official IXYS documentation, as standard listings often reference the similar MCC94-22IO1B variant. Confirm that the 2.2 kV rating aligns with system requirements. Request the latest datasheet to validate pinout compatibility and thermal characteristics before finalizing procurement orders.

Selection Notes

Select this component when a 94 A continuous current and 2.2 kV blocking voltage are required in a compact TO-240AA form factor. Ensure the gate drive circuit can supply at least 150 mA to guarantee reliable triggering. Verify that the mounting interface accommodates the screw mount style and that the thermal management system supports operation up to 125 C junction temperature.

Part Context

This module is part of the IXYS MCC94 series, which focuses on high-performance silicon thyristors for industrial applications. The series typically offers variants with different voltage ratings while maintaining consistent current capabilities and packaging standards. This specific model represents a high-voltage option within the lineup, suitable for demanding power electronics environments.

Replacement Considerations

Direct substitutes may include other IXYS MCC94 series modules with compatible current ratings but differing voltage specifications, such as the MCC94-18IO1B or MCC94-22IO1B. Cross-compatibility requires careful verification of voltage derating and gate trigger characteristics. Alternative manufacturers should be evaluated based on identical package dimensions and thermal resistance values.
