- Motor speed control applications
Procurement Notes
Verify the specific suffix against official Littelfuse documentation to confirm exact electrical characteristics. Ensure the ordering code matches the required gate sensitivity and voltage rating for your circuit design before procurement.
Selection Notes
Select this component when a high-voltage SCR with low gate drive requirements is needed in a small footprint. Verify that the 800mA RMS current capability meets the load requirements and that the SOT-223-3 package fits the PCB layout constraints.
Part Context
This part belongs to the SxX8xSx family of SCRs, which are characterized by their robust construction and suitability for general-purpose thyristor applications requiring surface mount technology.
Replacement Considerations
Check for direct substitutes within the same Littelfuse series or equivalent parts from other manufacturers offering identical voltage, current, and package specifications.
