Procurement Notes
Verify the exact current rating (550A vs 850A) against the official datasheet before procurement, as variations exist across similar part numbers. Confirm RoHS compliance status directly with the manufacturer documentation. Ensure the TO-200AC mounting interface matches your existing thermal assembly specifications to avoid integration issues during installation.
Selection Notes
Select this component when a 1200V SCR module is required for phase control applications. Consider the TO-200AC form factor for its established thermal performance in high-current scenarios. Evaluate the gate trigger characteristics against your control circuit capabilities to ensure proper turn-on reliability under varying load conditions.
Part Context
This module belongs to the T720 series of silicon controlled rectifiers from Powerex Inc. The series is engineered for heavy-duty power electronics, providing a balance of high voltage endurance and significant current handling capacity within a standardized mechanical footprint widely used in industrial power conversion equipment.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct replacements by matching the 1200V voltage rating, TO-200AC package dimensions, and equivalent current handling capabilities.
