SCRs - Modules Procurement Notes

Verify the specific version suffix against official datasheets to confirm the exact voltage rating, as the MCC/MCD series spans multiple voltage classes. Confirm mounting torque specifications (M5: 2.5-5 Nm) during installation to ensure mechanical integrity and proper thermal contact.

SCRs - Modules Selection Notes

Select this module based on its 1800 V blocking capability and 500 A RMS current handling. Evaluate thermal management requirements using the provided transient thermal impedance curves. Ensure the application circuit can handle the specified di/dt and dv/dt critical limits to prevent device failure.

SCRs - Modules Part Context

This component belongs to the IXYS MCC/MCD 310 series of thyristor modules. The series offers standardized international packaging and includes variants with different voltage ratings ranging from 800 V to 2200 V. The MCD designation specifically indicates a thyristor/diode configuration within this family.

SCRs - Modules Replacement Considerations

Cross-reference with other IXYS MCD310 variants such as MCD310-16IO1 or MCD310-14IO1 if lower voltage ratings are acceptable. Verify that any substitute maintains the same Y2-DCB package dimensions and terminal layout for mechanical compatibility.
