SCRs - Modules Procurement Notes

Verify the specific voltage suffix in the part number to confirm the rated voltage; the '20' indicates a 2000 V rating. Confirm that the required package type matches the MCO module form factor. Ensure compatibility with the specified mounting torque values for the M6 and M8 terminals during installation. Check for UL registration requirements if applicable to your region.

SCRs - Modules Selection Notes

Select this component when high surge current capability and robust thermal cycling performance are required. The planar passivation offers improved reliability compared to older technologies. Consider the specific conduction angle requirements as thermal resistance varies significantly between DC and pulsed operations. Verify that the system can accommodate the physical dimensions and weight of the module.
