Diotec Semiconductor product offering
Product offeringCore offering
Diotec Semiconductor AG manufactures and sells discrete semiconductor components for industrial, automotive, and energy applications. Its product portfolio includes diodes, rectifiers, MOSFETs, transistors, voltage regulators, and protection devices such as TVS and Zener diodes. The company serves electronics designers and manufacturers requiring reliable discrete power and signal conditioning components.
Product overview
Diotec Semiconductor offers a comprehensive portfolio of discrete semiconductor solutions organized into six core product families: Diodes (standard, Zener, Schottky, fast recovery), Rectifiers (single-phase and three-phase bridges), Regulators (linear and shunt), Transistors (BJTs), MOSFETs (Advanced Trench and SiC-MOSFETs), and Protection devices (TVS/ESD). The company provides both standard products and customized solutions where customers can specify chip design, package type, and lead configuration. Production facilities in Germany, Slovenia, China, and India support over 6,000 different part numbers, with a focus on high availability and fast worldwide delivery. Recent focus areas include 48V battery backup systems for AI data centers, electric vehicle charging, and industrial power supply applications.

Diotec Semiconductor competitors and assessment
Company assessmentDirect peers
- Vishay Intertechnology: Vishay is one of the world's largest manufacturers of discrete semiconductors (diodes, rectifiers, MOSFETs, optoelectronics) and passive components, serving the same industrial, automotive and power conversion customers as Diotec.
- Diodes Incorporated: Diodes Incorporated is a U.S.-headquartered manufacturer of discrete, analog and mixed-signal semiconductors, with a catalog (diodes, rectifiers, MOSFETs, transistors, protection devices) that closely mirrors Diotec's. Both companies pursue a broad-line discrete semi strategy through global distribution.
- ROHM Semiconductor: ROHM is a Japanese power and discrete semiconductor specialist with strong MOSFET, IGBT, SiC and diode portfolios targeted at automotive, industrial and consumer applications — directly overlapping Diotec's product and customer focus.
- Nexperia: Nexperia is a focused discrete semiconductor manufacturer (diodes, MOSFETs, bipolar transistors, rectifiers) with high-volume European and Asian production, targeting the same automotive, industrial and consumer customers as Diotec.
Broad incumbents
- STMicroelectronics: STMicroelectronics is a major European semiconductor incumbent with extensive discrete power, SiC and protection device offerings targeted at automotive, industrial and energy customers — directly overlapping Diotec's verticals from a much larger base.
- Microchip Technology: Microchip Technology is a broad-line semiconductor company whose discrete and power management products compete with Diotec's MOSFETs, rectifiers and protection devices in industrial and automotive applications.
- Infineon Technologies: Infineon is the global leader in power semiconductors, offering MOSFETs, IGBTs, SiC, diodes and protection devices across automotive, industrial and renewable energy. It competes with Diotec in most served segments from a vastly larger R&D and capacity base.
- Onsemi (ON Semiconductor): Onsemi is a broad-line U.S. semiconductor incumbent with a large discrete power and protection portfolio (MOSFETs, IGBTs, TVS, diodes) serving industrial, automotive and AI power applications that overlap Diotec's served markets.
- Toshiba Electronic Devices & Storage: Toshiba Electronic Devices is a broad-line Japanese semiconductor incumbent with discrete power (MOSFETs, IGBTs, diodes), automotive and industrial product lines that overlap Diotec's catalog and served applications.
Emerging players
- Micross Components: Micross is a specialty semiconductor distributor and value-add provider of discrete and hi-rel components serving industrial, defense and aerospace customers — comparable niche distribution-plus-customization motion to Diotec's customized discrete solutions.
