Triacs Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct packaging and variant selection. Confirm RoHS compliance status and REACH restrictions prior to integration. Cross-reference the datasheet revision date to validate current technical parameters and pinout configurations before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 12 A continuous current capacity are required for AC switching tasks. The TO-220A package facilitates efficient heat dissipation compared to smaller surface-mount alternatives. Ensure the application's peak current demands remain within the non-repetitive surge limits defined in the official specification sheet.

Triacs Part Context

This part belongs to the SST series of TRIACs from SMC Diode Solutions, which provides various voltage and current ratings for industrial and consumer electronics. The SST12A-800CW specifically addresses mid-power AC control needs, offering a balance between high voltage handling and significant current capacity in a standard through-hole form factor.

Triacs Replacement Considerations
