- Enhanced circuit protection capabilities via high surge voltage handling
- Designed for use in circuit breaker applications requiring reliable latching behavior
Scrs Applications
- Circuit breaker implementations
- Overvoltage protection circuits
- Electronic component protection systems
Scrs Procurement Notes
Verify the specific ordering suffix, as variants such as TS110-7A1-AP may exist with distinct packaging or process specifications. Confirm current availability status, as this component has been identified as scheduled for obsolescence by the manufacturer. Ensure compatibility with existing board layouts due to the TO-92 mounting type. Cross-reference official datasheets for precise thermal and electrical limits before finalizing procurement decisions.
Scrs Selection Notes
Select this component when designing circuits that require robust overvoltage protection with minimal gate drive requirements. The sensitive gate characteristic makes it appropriate for scenarios where available trigger current is restricted. Consider the 700V blocking capability and 1.25A continuous current rating against system load demands. Evaluate the TO-92 package constraints for thermal management and physical space limitations within the target assembly.
Scrs Part Context
This SCR belongs to the TS110-7 series from STMicroelectronics, which is engineered for sensitive gate operation. The series is specifically optimized for circuit breaker applications where gate current resources are constrained. It serves as a discrete thyristor solution for protecting downstream electronics from transient voltage spikes and fault conditions.
Scrs Replacement Considerations
Public documentation indicates the TS110-7A1-AP as a related variant within the same series. Verify if alternative part numbers are officially confirmed substitutes by the manufacturer. Check for functional equivalence in voltage ratings, current handling, and package dimensions before substitution.
