Thyristors
Thyristors are four-layer semiconductor devices (SCRs, TRIACs, DIACs) used for controlled AC power switching in motor speed controls, dimmers, soft starters, and industrial heaters. Once triggered, thyristors remain latched in the conducting state until current drops below the holding threshold, making them ideal for phase-controlled AC power regulation.

How to Choose Thyristors
A practical selection framework for Thyristors covering specifications, packaging, lifecycle, and sourcing on Octatronics.
Define electrical and environmental requirements
Start with the required function and operating conditions for Thyristors, then lock in critical parameters such as breakover voltage, on-state current, gate trigger current, holding current, and dv/dt capability. Match these against datasheet limits, not catalog summaries alone.
Validate package and land pattern compatibility
Confirm the Thyristors package matches your PCB footprint, pick-and-place constraints, and moisture sensitivity handling. Verify reel/tape or tube packaging for production.
Check lifecycle, compliance, and alternates
Review lifecycle status (Active, NRND, EOL), RoHS, and approved alternate sources for Thyristors before committing to high-volume builds. Use Octatronics cross-reference data when a drop-in replacement is needed.
Compare manufacturers and request pricing
Filter Thyristors by manufacturers such as onsemi and Vishay, compare key specs side by side, then submit an RFQ with quantity, target delivery, and traceability requirements.
