Overview
The Littelfuse S6S1RP is a silicon-controlled rectifier (SCR) from the SxSx series, designed for surface-mount applications in the DO-214AB-2 package. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current of 800 mA. The device has a maximum gate trigger voltage of 800 mV and a gate trigger current of 12 uA. It operates within a temperature range of -40 C to +110 C, with a forward voltage of 1.7 V and a holding current of 5 mA maximum.
Feature Summary
- Surface-mount construction in a compact DO-214AB-2 package for automated PCB assembly
- Low gate trigger current requirement suitable for sensitive sensing circuits
- High thermal stability with operation up to 110 C
Applications
- AC power sensing interfaces
- Solid-state relay driver circuits
- Lighting control systems
Procurement Notes
Verify the specific Littelfuse datasheet for the S6S1RP to confirm RoHS compliance status and REACH SVHC declarations before integration. Ensure the ordering suffix matches the required tape and reel or cut tape packaging format. Cross-reference the manufacturer part number against authorized distributor catalogs to validate authenticity and traceability.
Selection Notes
Select this component when a low-current SCR is needed for surface-mount designs requiring 600 V blocking capability. Compare the 12 uA gate trigger current against alternative devices if driving circuitry has limited output current. Verify that the 800 mA RMS current rating meets the load requirements and that the DO-214AB-2 footprint fits the board layout constraints.
Part Context
The S6S1RP belongs to the Littelfuse SxSx series of SCRs, which are engineered for general-purpose switching and sensing applications. This series offers various voltage and current ratings in standardized surface-mount packages to facilitate design flexibility across different industrial and consumer electronic platforms.
Replacement Considerations
Check for direct pin-compatible substitutes within the same SxSx family, such as the S6S2RP, noting differences in gate trigger current specifications.
