DIACs, SIDACs Procurement Notes

This component is classified as obsolete by the manufacturer. Availability is limited to existing stock or surplus channels rather than direct production runs. Buyers should verify the authenticity and condition of available units carefully. Distribution through authorized channels may be restricted due to the end-of-life status. Alternative sourcing strategies or equivalent replacements should be evaluated for long-term supply chain stability.

DIACs, SIDACs Selection Notes

Engineers selecting this part must account for its obsolete status when designing new products. The specific 220-250V breakover voltage range suits applications requiring precise triggering thresholds. The 1A current rating defines the maximum sustainable conduction level during operation. Designers should ensure the thermal management plan accommodates the specified junction temperature limits under worst-case load conditions.
