SCRs - Modules Procurement Notes

Verify the specific circuit configuration code 'H' corresponds to the SCR/diode doubler circuit with positive control before procurement. Confirm that the required voltage rating aligns with the '14' suffix indicating 1400 V. Ensure mounting hardware specifications match the TO-240AA case style requirements. Validate thermal interface material compatibility for the specified thermal resistance values.

SCRs - Modules Selection Notes

Select this component when a doubler circuit topology with positive control is required in high voltage environments. The 95 A average current rating suits moderate power applications. Consider the 1400 V blocking capability for systems requiring robust off-state voltage handling. Evaluate the thermal management needs based on the 0.22 °C/W junction-to-case thermal resistance per leg.
