TRIACs
TRIACs (Triode for Alternating Current) are bidirectional thyristors that switch AC current in both directions, widely used in light dimmers, fan speed controllers, AC motor soft starters, and heating element controllers. Key selection parameters include breakover voltage, on-state RMS current, gate trigger current, dI/dt, and dV/dt ratings.

How to Choose TRIACs
A practical selection framework for TRIACs covering specifications, packaging, lifecycle, and sourcing on Octatronics.
Define electrical and environmental requirements
Start with the required function and operating conditions for TRIACs, 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 TRIACs 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 TRIACs before committing to high-volume builds. Use Octatronics cross-reference data when a drop-in replacement is needed.
Compare manufacturers and request pricing
Filter TRIACs by manufacturers such as onsemi and Vishay, compare key specs side by side, then submit an RFQ with quantity, target delivery, and traceability requirements.

Frequently Asked Questions
Octatronics can help source a wide range of TRIACs from major manufacturers worldwide, including active production parts, long-lead-time items, and hard-to-find components.
Yes. You can submit a single part number or upload a BOM with multiple parts. Our team will check stock, date code, lead time, and pricing for each item.
Availability depends on the specific part number and supplier source. For important orders, buyers can request packaging photos, labels, date code information, and traceability documents.
Yes. Octatronics supports sourcing for active, end-of-life, obsolete, and hard-to-find components through our global supplier network.
Please provide the part number, manufacturer, quantity, required date code, target price, delivery country, and whether original packaging or COC is required.
