Triacs Procurement Notes

Verify the specific suffix 'R4' against official Littelfuse documentation to confirm package type and compliance status. Ensure the component matches the required voltage and current ratings for the target circuit design before procurement.

Triacs Selection Notes

Select this component for low-voltage AC switching tasks requiring robust thermal performance via the TO-220AB housing. Confirm that the 200V rating aligns with the system's peak line voltages and that the 8A current capacity meets the load requirements without derating issues.

Triacs Part Context

This part belongs to the Teccor brand Triac family, designed for general-purpose AC power control. It serves as a bidirectional solid-state switch, offering an alternative to mechanical relays in applications demanding high cycle life and fast response times for consumer and industrial electronics.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Generic replacements must match the 200V/8A specifications and TO-220AB footprint while maintaining compatible gate trigger characteristics.
