Procurement Notes
Verify the specific part status before procurement, as this item may be discontinued at major distributors. Confirm RoHS compliance requirements against project specifications, noting that some listings indicate varying compliance statuses. Ensure the TO-220 Non-Isolated Tab package matches the thermal and mechanical design constraints of the target assembly.
Selection Notes
Select this SCR based on the 400V blocking voltage and 6A current requirements. Consider the TO-220 package for adequate heat dissipation in non-isolated mounting scenarios. Evaluate the 800mV gate trigger voltage for compatibility with driving logic levels. Compare against other low-power SCRs in the 400V to 1200V range if higher voltage ratings are needed.
Part Context
This component belongs to the Littelfuse low-power SCR family, which offers voltage capabilities up to 1200V. These devices typically feature UL recognition for isolation voltages up to 2500Vrms. The series is characterized by glass-passivated junctions and robust surge handling, making them suitable for various industrial and commercial power control tasks requiring reliable thyristor performance.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. When seeking alternatives, verify that any replacement SCR matches the 400V off-state voltage, 6A on-state current, and TO-220 package type. Cross-reference gate trigger specifications to ensure circuit compatibility.
