MCMA200PD1800YB

Overview

The IXYS MCMA200PD1800YB is a silicon-controlled rectifier (SCR) module designed for high-power industrial applications. It features a rated average on-state current of 200A and a repetitive peak off-state voltage of 1800V. The device utilizes a TO-240AA package with panel mounting capabilities, ensuring robust mechanical stability in demanding environments. Key electrical characteristics include a non-repetitive surge current rating of 3.5kA and a maximum gate trigger current of 200mA. The module operates within a temperature range of -40°C to +125°C, providing reliable performance for line-frequency applications requiring high voltage blocking and significant current handling capacity.

Feature Summary

• High voltage blocking capability suitable for demanding power conversion systems
• Robust thermal management through direct panel mounting design
• Standardized pin configuration for simplified integration into existing circuits

Applications

• Industrial motor drives and variable frequency drives
• High-power DC-DC converters and power supplies
• Static switchgear and circuit protection systems

Procurement Notes

Verify the specific suffix 'YB' against official IXYS documentation to confirm exact binning or testing variations. Ensure compatibility with standard TO-240AA mounting hardware. Confirm that the 1800V rating aligns with system transient requirements. Check for RoHS compliance status if required by project specifications. Validate gate trigger parameters against the driving circuit capabilities.

Selection Notes

Select this component when applications require a balance of high current density and high voltage isolation in a compact form factor. The 200A rating supports substantial load currents while the 1800V rating provides adequate margin for grid-connected or industrial supply voltages. Consider the thermal resistance and mounting pressure requirements during mechanical design. Evaluate the gate drive requirements against available control signals to ensure reliable triggering under all operating conditions.

Part Context

This module belongs to the IXYS MCMA series of thyristor modules, which are engineered for general-purpose high-power switching. The series typically employs planar passivated chips for improved reliability and reverse blocking capability. These components are widely used in industries such as welding, heating, and power transmission where robust semiconductor switches are essential for efficient energy conversion and control.

Replacement Considerations

Direct replacements may include other IXYS SCR modules with similar current and voltage ratings in the TO-240AA package, such as the MCMA200P1600TA or MCMA200UJ1800ED. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference with other manufacturers offering equivalent TO-240AA SCR modules, ensuring that gate trigger parameters and surge ratings meet or exceed original specifications.
