Overview
The MCC21-16IO8B is a silicon thyristor module manufactured by IXYS, designed for high-power industrial applications. It features a TO-240AA screw-mount package and operates within a temperature range of -40°C to +100°C. The device has a rated output current of 21 A and a maximum reverse voltage of 1400 V. Key electrical parameters include a gate trigger current (Igt) of 65 mA and a maximum holding current (Ih) of 100 mA. The unit weighs approximately 83 g and complies with RoHS standards.
Feature Summary
- High-voltage silicon thyristor construction for robust power switching
- Screw-mount installation in a compact TO-240AA package
- Low gate trigger current requirements for efficient control
Applications
- Industrial motor drives and variable frequency drives
- DC power supply rectification circuits
- General-purpose AC/DC conversion systems
Procurement Notes
Verify the specific model suffix against official IXYS documentation to confirm exact ratings. Ensure compatibility with existing thermal management solutions due to the TO-240AA form factor. Confirm that the 21 A continuous current rating meets the design requirements for the intended load conditions before finalizing procurement.
Selection Notes
Select this component when a 1400 V blocking capability and 21 A current handling are required in a standard screw-mount configuration. Compare the 65 mA gate trigger specification against available drive circuit capabilities. Consider the 100 mA holding current limit to ensure reliable turn-off in the specific application circuit topology.
Part Context
This part belongs to the IXYS MCC series of discrete semiconductor modules. The series is characterized by silicon technology and standardized packaging for easy integration into power electronics assemblies. The MCC21 variant specifically targets medium-power applications requiring reliable thyristor performance.
Replacement Considerations
Publicly confirmed substitute part numbers for the MCC21-16IO8B were not identified in the provided source material. Verify pinout and thermal characteristics if considering alternative manufacturers' thyristors with similar voltage and current ratings.
