Procurement Notes

Verify that the specific ordering suffix matches the required package variant and temperature range specifications. Confirm that the component meets all relevant safety certifications for the intended end-use application. Ensure proper handling procedures are followed during installation to maintain device integrity and performance reliability.

Selection Notes

Select this component when designing circuits requiring high voltage blocking and moderate current handling capabilities. Consider the thermal resistance of the ITO-220AB package for adequate heat sinking requirements. Evaluate the gate trigger sensitivity against the driving circuit's output capabilities to ensure consistent turn-on performance under varying load conditions.

Part Context

This part belongs to the Sxx08x series of low power SCRs from Littelfuse, which supports voltages up to 1200 V. The series is engineered for general-purpose power control tasks where reliable switching and durability are critical. It complements the manufacturer's broader portfolio of thyristors and protection devices for industrial and consumer electronics markets.

Replacement Considerations

Consult official Littelfuse documentation for verified cross-reference part numbers. Do not assume functional equivalence with generic SCR components without verifying pinout, voltage ratings, and thermal characteristics against the original specification sheet.
