Updated at April 29, 2026
Infineon Technologies is a globally recognized leader in semiconductor solutions, renowned for driving innovation in power management, energy efficiency, and modern mobility. With a strong legacy of engineering excellence, the company provides highly reliable components designed to meet the rigorous demands of industrial, automotive, and advanced commercial applications. The core of our Infineon portfolio is centered on their industry-leading discrete semiconductors. We offer an extensive selection of single and dual MOSFETs, alongside a robust range of single IGBTs and advanced IGBT modules. These flagship power transistors are essential for high-efficiency power conversion and motor control, providing engineers with superior thermal performance and minimized switching losses. Beyond advanced field-effect transistors, the selection includes a comprehensive array of diodes and rectifiers, heavily featuring Schottky diodes, as well as fast-recovery and RF/PIN diodes. This power foundation is further supported by bipolar transistors, intelligent power modules, and thyristor SCR modules, delivering the critical building blocks required for complex power system designs. To support broader system integration, the portfolio also encompasses specialized solutions such as solid-state relays, AC/DC LED driver ICs, and Bluetooth communications modules. From high-power industrial rectifiers to wireless connectivity adapters, Infineon equips designers with the precision components needed to build efficient, scalable, and fully connected electronic systems.
About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
