SCRs - Modules Procurement Notes

Verify the specific circuit configuration code 'L' corresponds to the SCR/diode doubler circuit with negative control before procurement. Confirm that the voltage code '10' matches the required 1000 V rating for the target application. Ensure mounting hardware complies with the specified torque requirements for the TO-240AA case style.

SCRs - Modules Selection Notes

Select this component when a negative control SCR/diode doubler topology is required. The 95 A current rating and 1000 V blocking voltage define the electrical limits. Consider the thermal resistance characteristics and the need for heatsink mounting compatible with the screw mount interface of the ADD-A-PAK package.
