Overview
The S6X8BS1RP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc., belonging to the SxX8xSx series. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (It RMS) of 800 mA. The device operates with a gate trigger current (Igt) of 200 uA and a gate trigger voltage (Vgt) of 800 mV maximum. It exhibits a forward voltage drop (Vf) of 1.7 V and a non-repetitive peak on-state current of 10 A. The component supports surface mount installation in a SOT-89-3 package, functioning within a temperature range from -40 C to +125 C.
Feature Summary
- Sensitive gate triggering capability for low-power control applications
- Surface-mount compatible design for automated assembly processes
- High thermal stability suitable for demanding operating environments
Applications
- AC power switching circuits
- Lighting control systems
- Motor speed regulation
Procurement Notes
Verify the specific suffix against official Littelfuse documentation to confirm exact electrical tolerances and packaging variations. Ensure the source provides the complete datasheet for the S6X8BS1RP variant rather than generic family data. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and traceability before procurement.
Selection Notes
Select this component when a compact SCR with 600 V blocking capability and 800 mA continuous current rating is required. The sensitive gate specification allows for direct interfacing with low-current logic outputs. Verify that the SOT-89-3 footprint aligns with the target PCB layout constraints and thermal management requirements.
Part Context
This device is part of the Littelfuse SxX8xSx series of silicon controlled rectifiers. The series offers various voltage and current ratings packaged in small form factors suitable for space-constrained designs. The S6X8BS1RP specifically addresses applications requiring moderate current handling with high voltage isolation in a surface-mount configuration.
Replacement Considerations
The S6X8BSRP is documented as a parameter-equivalent alternative. Verify pinout compatibility and ensure all electrical parameters meet or exceed the original design requirements before substitution.
