Overview
The S6X8BSRP1 is a silicon controlled rectifier manufactured by Littelfuse Inc., designed for surface mount applications in the SOT-89 package. It features a rated repetitive off-state voltage of 600 V and an on-state RMS current of 800 mA. The device is classified as a sensitive gate SCR, requiring a maximum gate trigger voltage of 800 mV and a maximum gate trigger current of 200 µA to initiate conduction. In the on-state, it exhibits a maximum forward voltage drop of 1.7 V at an average on-state current of 510 mA. The component supports non-repetitive surge currents of up to 10 A and maintains a holding current of 5 mA. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Sensitive gate architecture enables reliable triggering with low gate drive requirements.
- Surface mount construction in a compact SOT-89 package facilitates automated PCB assembly.
- High thermal stability allows operation across extended industrial temperature ranges.
Applications
- AC/DC motor control circuits
- Power supply regulation systems
- Solid state switching applications
Procurement Notes
Verify the specific suffix '1' against the manufacturer's official datasheet to confirm packaging configuration and tape-and-reel specifications. Ensure the ordered part matches the exact electrical ratings required for the target circuit design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.
Selection Notes
Select this component when a surface mount SCR with 600 V blocking capability and 800 mA continuous current handling is required. The sensitive gate characteristic makes it suitable for low-power control signals. Verify that the SOT-89 footprint fits the board layout constraints and that the thermal management strategy accommodates the specified operating temperature limits.
Part Context
This component belongs to the SxX8xSx series of silicon controlled rectifiers from Littelfuse. The series provides various voltage and current ratings in standardized surface mount packages. The S6X8BSRP1 specifically addresses applications needing moderate power switching in a compact form factor, serving as a bridge between through-hole reliability and modern surface mount density.
Replacement Considerations
The S6X8BSRP is listed as a parameter-equivalent substitute. Verify if the base model meets all functional requirements without the specific packaging or suffix variations associated with the '1' designation.
