Procurement Notes
Verify the specific suffix 'B' against the manufacturer's latest datasheet to confirm pinout compatibility and material composition changes. Ensure the ordering quantity aligns with factory packaging standards to avoid partial reel issues. Cross-reference the RoHS status with regional compliance requirements before finalizing procurement orders.
Selection Notes
Select this module when a 2 kV blocking voltage and 94 A continuous current are required within a TO-240AA form factor. Evaluate the thermal resistance characteristics against the system's heatsink capabilities to ensure the junction temperature remains within the +125°C limit during peak operation cycles.
Part Context
This component belongs to the IXYS MCC/MCD series of discrete thyristor modules. These devices are engineered for reliability in high-stress power electronics. The series offers various voltage and current combinations to support diverse industrial power conversion needs while maintaining standardized mounting interfaces.
Replacement Considerations
Direct cross-compatibility with other manufacturers requires verification of pin assignments and thermal interface dimensions. Review the forward voltage and gate trigger specifications to ensure equivalent switching performance. Consult official substitution guides for confirmed equivalents within the same voltage and current class.
