SCRs - Modules Procurement Notes

Verify the specific circuit configuration code 'H' corresponds to the required SCR/diode doubler arrangement with positive control. Confirm that the 800 V voltage rating aligns with the system's maximum repetitive peak reverse voltage requirements. Ensure mounting hardware complies with the specified torque values for the TO-240AA case style.

SCRs - Modules Selection Notes

Select this component when a doubler circuit topology with positive control is required. The 95 A current rating must be validated against the application's conduction angle and thermal management capabilities. Consider the 800 V blocking voltage relative to the peak line voltage and transient conditions in the target circuit design.
