Discrete Semiconductors
Discrete semiconductors are individual active components — diodes, transistors, MOSFETs, IGBTs, thyristors, and rectifiers — that perform switching, rectification, amplification, and voltage regulation in virtually every power and signal circuit. Octatronics indexes tens of thousands of discrete devices from Vishay, Nexperia, onsemi, Infineon, ROHM, Toshiba, and Diodes Incorporated with parametric search, package filtering, and RFQ support.

32 productsAbout Discrete Semiconductors
Unlike integrated circuits that combine multiple functions on one die, discrete semiconductors perform a single electrical function per device — making them fundamental building blocks that engineers combine to create custom power stages, protection circuits, signal switches, and amplifier topologies tailored to specific system requirements.
This category encompasses Diodes (Schottky, Zener, TVS, rectifier, and switching), Transistors (BJTs, MOSFETs, JFETs, IGBTs), and Thyristors (SCRs, TRIACs, DIACs). Discrete devices are selected based on voltage and current ratings, switching speed, on-resistance (RDS(on)), forward voltage drop, thermal characteristics, and package footprint.
On Octatronics, filter discrete semiconductors by device type, polarity, voltage/current class, package (SOT-23, TO-220, D2PAK, QFN), and automotive AEC-Q101 qualification. Compare parametric data across manufacturers and submit RFQs for prototyping or production volumes.
Frequently Asked Questions
Octatronics can help source a wide range of Discrete Semiconductors 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.
