Leading Discrete Semiconductor Manufacturers on Octopart

Sourcing from the right discrete semiconductor manufacturers determines the long-term reliability of your end product. Octopart gives you direct access to semiconductor components from Infineon, onsemi, Vishay, and Diodes Inc., among others. We pull inventory data directly from over 400 distributors, so you see authorized stock counts and lead times for every discrete semiconductor listed. Filtering by manufacturer, package type, or electrical parameter helps you lock in the exact part your bill of materials requires. Our parametric search tools let procurement agents and engineers narrow results by voltage rating, current capacity, and mounting style without jumping between supplier websites.

Discrete Semiconductor Modules for High-Power Applications

Engineers working on power conversion, motor drives, and industrial automation frequently specify discrete semiconductor modules that integrate multiple semiconductors into a single package. These modules reduce parasitic inductance and simplify thermal management compared to assembling individual discrete semiconductor devices on a PCB. With Octopart, you can source IGBTs, MOSFETs, BJTs, and more from leading manufacturers.
