Company Description
Vishay Intertechnology, Inc. (NYSE: VSH) is a manufacturer in the semiconductor and related device industry that focuses on discrete semiconductors and passive electronic components. According to company disclosures, Vishay manufactures one of the world’s largest portfolios of these components, which are used in automotive, industrial, computing, consumer, telecommunications, power supply, military, aerospace, and medical markets. The company serves customers worldwide and is described in its news releases as a Fortune 1000 company listed on the New York Stock Exchange.
Vishay’s product offering is organized into two broad classes: semiconductors and passive components. Within these, the company’s operating segments include metal oxide semiconductor field-effect transistors (MOSFETs), diodes, optoelectronic components, resistors, inductors, and capacitors. Information from its profile notes that revenue mainly comes from resistors, which are basic components used in electronic circuitry to adjust and regulate levels of voltage and current.
Semiconductor devices and sensors
The company’s semiconductor activities include devices marketed under Vishay Semiconductors. Recent product announcements highlight areas such as transmissive sensors for position sensing and optical encoding, ambient light sensors, solid-state relays, and silicon carbide (SiC) MOSFET power modules. These products are used in applications that span industrial automation systems and drives, consumer products and appliances, telecom equipment, automotive systems, energy storage, and battery management.
For example, Vishay has introduced transmissive sensors in compact surface-mount packages for position sensing and optical encoding, including single-channel and dual-channel devices that can detect motion, speed, and direction. The company also offers an AEC-Q100 qualified ambient light sensor in a rectangular surface-mount package, designed for use in automotive display backlight controls, infotainment systems, rearview mirror dimming, interior lighting control systems, and heads-up displays. In addition, Vishay has released a 1500 V Automotive Grade 1 Form A solid-state relay in a surface-mount package for 800 V battery monitoring systems in automotive, energy storage, and industrial applications.
Vishay’s SiC MOSFET power modules combine silicon carbide MOSFETs, intrinsic SiC diodes, and integrated NTC thermistors for temperature sensing. These modules are designed for medium to high frequency applications in automotive, energy, industrial, and telecom systems, including solar inverters, electric and hybrid vehicle chargers, motor drives, welding equipment, DC/DC converters, uninterruptible power supplies (UPS), HVAC systems, large scale battery storage systems, and telecom power supplies.
Passive components: resistors, inductors, capacitors, and thermistors
On the passive component side, Vishay produces resistors, inductors, capacitors, and thermistors. Company information notes that resistors are a major revenue contributor. Vishay has announced thin film chip fuses designed to ensure circuit continuity with minimal resistance and reliable interruption under overload conditions. These fuses are offered in multiple case sizes, cover a range of rated currents, and provide fast or very fast acting protection, allowing designers to match fuse behavior to circuit protection requirements.
The company also extends its capacitor portfolio with miniature snap-in power aluminum electrolytic capacitors in the 193 PUR-SI series, including devices with voltage ratings up to 600 V. These capacitors are designed for smoothing, buffering, and DC-link filtering in switch mode power supplies, electric and hybrid vehicle chargers and battery management systems, industrial motor drives, air conditioners, solar inverters, medical equipment, UPS systems, and welding equipment. They are described as polarized aluminum electrolytic capacitors with a non-solid electrolyte, capable of handling ripple currents and long useful life at elevated temperatures.
Vishay’s inductors division produces power inductors, including its IHLP family of molded composite inductors. A new factory in Gomez Palacio, Durango, Mexico, has been certified to the IATF 16949:2016 quality standard for magnetic inductors, as well as ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 for its management systems. The facility also carries a LEED certification for environmental performance.
In temperature sensing, Vishay offers AEC-Q200 qualified glass protected NTC thermistors in 0402 case sizes. These devices combine high beta values with specific resistance values at 25 °C and tight tolerances, enabling precise temperature sensing, protection, and compensation over a wide temperature range. They are described as suitable for automotive LED modules, electronic control units, sensor clusters, battery packs, camera, radar, and lidar modules, energy meters, office equipment, and industrial smoke and fire detectors.
Target markets and applications
Across its portfolio, Vishay emphasizes that its discrete semiconductors and passive components are essential to designs in multiple end markets. Company descriptions consistently cite the automotive, industrial, computing, consumer, telecommunications, military, aerospace, and medical sectors. Specific applications mentioned in product releases include:
- Electric and hybrid vehicle battery management systems, chargers, on-board chargers, and 800 V battery monitoring systems

Quality, certifications, and recognition
Vishay highlights quality and reliability in its product and manufacturing disclosures. The company references Automotive Grade qualifications such as AEC-Q100 and AEC-Q200 for certain sensors and thermistors, and AEC-Q102 for its solid-state relay. Its new inductor factory in Mexico is certified to IATF 16949:2016 for magnetic inductors, ISO 9001:2015 for all products, ISO 14001:2015 for environmental management, and ISO 45001:2018 for occupational health and safety. The facility also has a LEED certification for green building practices.
Several Vishay products have received industry recognition. The SGTPL-28 series of space-grade planar transformers has been honored with an AspenCore EE Awards Asia award in the Discrete Product category. These transformers are described as 150 W low profile, space-grade planar transformers with multiple output secondaries, optimized for 28 V input forward converters in aerospace and defense applications and meeting requirements such as MIL-PRF-27 level T, INST-EEE-002, and MIL-STD-981. The VEML4031X00 ambient light sensor has received an AspenCore World Electronics Achievement Award in the Sensor category, noted as the industry’s first AEC-Q100 qualified rectangular ambient light sensor.
