Diodes
Diodes are two-terminal semiconductor devices that allow current to flow predominantly in one direction, performing rectification, voltage clamping, signal switching, and voltage regulation functions. This category covers rectifier diodes, Schottky barrier diodes, Zener voltage regulators, switching diodes, and TVS protection diodes from Vishay, Nexperia, onsemi, Diodes Incorporated, and ROHM.

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