MCC200-18IO1

Overview

The IXYS MCC200-18IO1 is a silicon-controlled rectifier module designed for high-power industrial applications. It features a TO-240AA package with seven pins and supports panel mounting via screw terminals. The device has a rated repetitive off-state voltage of 1800 V and an RMS on-state current of 200 A. It can withstand a non-repetitive surge current of 3.6 kA. Key electrical parameters include a maximum gate trigger current of 150 mA, a holding current of 200 mA, and a peak on-state voltage of 1.1 V. The module operates within a temperature range of -40°C to +100°C.

Feature Summary

• High power handling capability with 200 A RMS current rating
• Robust surge tolerance up to 3.6 kA for transient protection
• Integrated thermal isolation in a compact TO-240AA housing

Applications

• Industrial motor drives and variable frequency drives
• High-voltage DC transmission systems
• Welding equipment power stages

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact electrical tolerances and pinout configurations. Ensure the supplier provides traceable documentation matching the manufacturer's specifications. Confirm compliance with RoHS directives if required by the project standards before finalizing orders.

Selection Notes

Select this component when an 1800 V blocking voltage and 200 A continuous current are required. Verify that the system's cooling capacity matches the thermal resistance of the TO-240AA package. Ensure the gate drive circuit can supply at least 150 mA to guarantee reliable triggering under all operating conditions.

Part Context

This part belongs to the MCC series of thyristor modules from IXYS, now part of Littelfuse. The series is engineered for robust performance in demanding power electronics environments. The MCC200-18IO1 specifically targets applications requiring high voltage isolation and significant current carrying capacity in a standardized footprint.

Replacement Considerations

Direct replacements must match the 1800 V rating, 200 A current, and TO-240AA package. Verify pin compatibility and thermal characteristics. Cross-reference with other manufacturers' high-power SCR modules offering similar surge ratings and gate trigger requirements.
