MCC72-14IO1B

Overview

The IXYS MCC72-14IO1B is a single-phase thyristor module designed for high-power industrial applications. It features an RMS on-state current of 72 A and a rated repetitive peak off-state voltage of 1400 V. The device utilizes a TO-240AA (Y5) screw-mount package, ensuring robust mechanical stability. Key electrical parameters include a maximum holding current of 200 mA and a gate trigger current of 150 mA. The forward voltage drop is specified at 1.34 V, while the operating temperature range spans from -40°C to +100°C.

Feature Summary

• Single-phase SCR configuration for phase control applications
• Screw-mount construction for secure thermal interface
• High thermal cycling capability within standard industrial ranges

Applications

• Industrial motor drives and variable frequency drives
• Resistive load control systems
• Power supply rectification circuits

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest datasheet to confirm pinout and terminal configuration. Ensure the procurement channel provides original manufacturer documentation to validate authenticity. Cross-reference the lot code with production notifications to avoid obsolete or modified versions.

Selection Notes

Select this component when a 72 A continuous current rating and 1400 V blocking voltage are required in a compact TO-240AA form factor. Evaluate the 1.34 V forward voltage for thermal management efficiency. Confirm that the 150 mA gate trigger requirement aligns with the available drive circuit capabilities.

Part Context

This module belongs to the IXYS MCC series of silicon-controlled rectifiers. The series offers various current ratings from 19 A to higher capacities, all sharing similar mounting styles. The MCC72 variant specifically bridges lower and higher power segments, providing a balance between current handling and physical footprint for medium-power industrial converters.

Replacement Considerations

Direct cross-compatibility requires matching the 72 A/1400 V specifications and TO-240AA package dimensions. Verify gate trigger characteristics and thermal resistance values before substitution. Consult official replacement lists for updated series equivalents if discontinuation occurs.
