- Surface-mount construction via TO-251 package for space-efficient integration
- Standard recovery profile optimized for phase control operations
Applications
- Phase control circuits
- Heating element regulation
- Motor speed controls
- Converters and rectifiers
Procurement Notes
Verify the specific ordering suffix to ensure the correct packaging configuration matches your assembly requirements. Confirm RoHS compliance status if environmental regulations apply to your production line. Cross-reference the manufacturer's latest datasheet to validate electrical parameters against your design specifications before finalizing procurement decisions.
Selection Notes
Select this component when a surface-mount SCR with 400 V blocking voltage and 8 A continuous current handling is required. Ensure the thermal management strategy supports the TO-251 package's dissipation capabilities. Consider the standard recovery time for compatibility with the intended switching frequency and load type within the target application environment.
Part Context
This part belongs to the Sxx08x series of SCRs from Littelfuse, which are engineered for uni-directional switch applications. The series offers a standardized form factor across various voltage ratings, allowing designers to maintain consistent layout practices while adjusting voltage specifications for different power system requirements.
Replacement Considerations
Consult official Littelfuse documentation for confirmed substitute part numbers within the same series or equivalent voltage/current ratings. Verify pinout compatibility and thermal performance metrics before substituting to ensure circuit integrity and reliable operation under identical load conditions.
