- Motor speed controls
Procurement Notes
Verify the specific ordering suffix to ensure the correct package variant and tape/reel configuration are selected. Confirm that the 200V voltage rating and 70A current capacity align with the target circuit requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the TO-218X footprint matches the PCB design constraints before procurement.
Selection Notes
Select this component when a low-power SCR with a 200V blocking capability is required. The 70A current rating suits moderate power loads in industrial or consumer electronics. Consider the TO-218X package for ease of manual assembly or wave soldering processes. Evaluate thermal management needs based on the continuous on-state current and ambient operating temperature conditions.
Part Context
This part belongs to the Low Power SCR series from Littelfuse, which covers devices up to 1200V. The S2070WTP represents a specific voltage and current combination within this family. It is engineered for embedded electronics and industrial equipment where reliable phase control is necessary. The series provides standardized solutions for various power levels.
Replacement Considerations
Direct substitutes must match the 200V, 70A, TO-218X specifications. Verify pinout compatibility and thermal resistance values. Cross-reference with other manufacturers' SCRs offering identical electrical ratings and package dimensions to ensure functional interchangeability without redesigning the host circuit.
