Triacs Procurement Notes

This specific part number is classified as End of Life (EOL) by the manufacturer. Availability is restricted to existing stock only, with no new production scheduled. Buyers should verify current inventory levels with authorized distributors immediately. Lead times are subject to stock depletion, and minimum order quantities may apply. Transitioning to alternative components is recommended for long-term supply chain stability.

Triacs Selection Notes

Select this component for low-power AC switching tasks requiring a compact surface mount footprint. Ensure the circuit design accommodates the 600 V blocking voltage and 4.0 A continuous current rating. Verify that the PCB layout matches the DPAK mechanical outline. Consider derating the current capacity if the operating ambient temperature exceeds standard conditions or if heatsinking is insufficient.

Triacs Part Context

The CQD-4M belongs to a series of surface mount silicon TRIACs manufactured by Central Semiconductor Corp. These devices are engineered for general-purpose AC control where space constraints necessitate surface mount packaging. The product line includes variants with different voltage ratings, such as the CQD-4N, which offers higher blocking voltage capabilities while maintaining similar current handling characteristics.

Triacs Replacement Considerations

No direct replacement part numbers are listed by the manufacturer. The official documentation indicates N/A for replacements, noting that availability is limited to stock only. Engineers must identify equivalent components from other manufacturers based on matching electrical parameters and package dimensions.
