Overview
The S6X8TSRP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse, belonging to the SxX8xS series. It features an 800 mA RMS on-state current and a 600 V rated repetitive off-state voltage. The device operates within a temperature range of -40°C to +125°C and utilizes a surface-mount SOT-223-3 package. Key electrical parameters include a gate trigger current of 200 µA, a forward voltage of 1.7 V, and a holding current maximum of 5 mA. It supports non-repetitive peak on-state currents of 10 A at 60 Hz.
Feature Summary
- Surface-mount construction in a compact SOT-223-3 package for automated PCB assembly
- Gate-controlled switching with low trigger current requirements for efficient drive circuits
- High thermal stability supporting operation up to +125°C junction temperature
Applications
- AC power control circuits
- Phase control applications
- General purpose switching
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging configuration. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Cross-reference the full part number with Littelfuse documentation to validate manufacturing origin and quality certifications.
Selection Notes
Select this component when a low-current SCR is required for surface-mount designs. Ensure the circuit can handle the 600 V blocking voltage and that the gate drive provides sufficient current above 200 µA. Verify thermal management capabilities for the SOT-223-3 package under expected load conditions.
Part Context
This device is part of Littelfuse's SxX8xS family of SCRs. The series offers various voltage and current ratings in standardized packages. The S6X8TSRP specifically addresses applications needing moderate current handling in a small form factor.
Replacement Considerations
Consult Littelfuse documentation for direct cross-references. Potential alternatives may include other SOT-223 SCRs from different manufacturers with matching 600 V and 800 mA ratings, provided pinouts and electrical characteristics are compatible.
