Procurement Notes

Verify the specific manufacturer part number against official IXYS documentation to ensure authenticity. Confirm that the TO-240AA package dimensions and screw mounting specifications match your mechanical design requirements. Check for RoHS compliance status if environmental regulations apply to your assembly process. Ensure storage conditions adhere to semiconductor handling standards to prevent moisture damage before soldering or mounting.

Selection Notes

Select this module when an 800V rating and 21A continuous current capacity are required for single-phase or bridge configurations. Compare the 65mA gate trigger current against your control circuit capabilities to ensure adequate drive strength. Consider the TO-240AA footprint for PCB or chassis layout constraints. Evaluate thermal dissipation needs based on the 100°C maximum operating temperature limit and expected ambient conditions.

Part Context

This component is part of the IXYS MCC series of discrete thyristor modules. It shares the TO-240AA package form factor with other variants in the lineup, such as the MCC21-14IO8B and MCC56-08IO8B. The series provides standardized mounting solutions for various current and voltage combinations, facilitating modular design approaches in power electronics systems requiring reliable silicon-controlled rectification.

Replacement Considerations

Publicly confirmed substitute part numbers for the MCC21-08IO8B were not identified in available documentation. Verify compatibility with alternative thyristor modules by matching the 800V reverse voltage, 21A output current, TO-240AA package type, and screw mount configuration. Consult manufacturer cross-reference guides for equivalent devices with identical pinouts and thermal characteristics.
