Overview
The S2008R is a standard recovery silicon controlled rectifier (SCR) from Littelfuse, rated for 8.0 A average on-state current and 200 V repetitive peak off-state voltage. It utilizes a TO-220 non-isolated tab package configuration suitable for through-hole mounting. This component belongs to the Low Power SCR series, designed for uni-directional switching applications requiring robust performance in power control circuits.
Feature Summary
- Non-sensitive gate construction for reliable triggering
- Electrically isolated package option available within the series
- Standard recovery characteristics for general purpose switching
Applications
- Phase control circuits
- Heating element regulation
- Motor speed controls
- Converters and rectifiers
Procurement Notes
Verify component availability status as the S2008R may be listed as obsolete or end-of-life by the manufacturer. Confirm that the TO-220 non-isolated tab package meets thermal and electrical isolation requirements for the specific design. Ensure ordering suffixes match the required lead time and packaging specifications provided in official distributor catalogs.
Selection Notes
Select this device for low-power uni-directional switching tasks where an 8 A current rating and 200 V blocking capability are sufficient. The non-sensitive gate feature simplifies drive circuit design compared to sensitive gate variants. Consider thermal management requirements associated with the TO-220 package when integrating into high-duty cycle applications.
Part Context
This part belongs to the Sxx08x series of low-power SCRs from Littelfuse, which covers ratings up to 1200 V. The series is engineered for compact power systems and industrial controls. The S2008R specifically addresses the 8 A / 200 V segment, offering a standardized solution for basic thyristor switching needs in consumer and industrial electronics.
Replacement Considerations
Check for direct cross-reference part numbers from Littelfuse or other manufacturers offering identical 8 A / 200 V TO-220 specifications. Verify pinout compatibility and thermal resistance values if substituting with components from different vendors to ensure equivalent performance.
