Procurement Notes
Verify the specific ordering suffix against official Littelfuse documentation to ensure correct package and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before finalizing procurement orders.
Selection Notes
Select this component when an 800 V rating and 1.25 A RMS current capacity are required in a surface-mount footprint. Ensure the application circuit provides sufficient gate drive current below 200 µA to utilize the sensitive gate feature effectively while maintaining thermal stability within the specified operating temperature range.
Part Context
This SCR belongs to the Sx02CSx family of Littelfuse thyristors, which are engineered for high-reliability power switching. The series emphasizes compact surface-mount solutions that integrate high voltage handling with sensitive gate characteristics, addressing space constraints in modern electronic designs without compromising performance under load.
Replacement Considerations
Consult Littelfuse official substitution guides for verified equivalents. Cross-reference key parameters such as VDRM, IT(RMS), IGT, and package dimensions to ensure functional compatibility during design updates or supply chain adjustments.
