6 terms

silicon carbide technical

"feature Vishay’s latest generation silicon carbide (SiC) MOSFETs in the industry-standard"

Silicon carbide is a hard, durable material made from silicon and carbon, often used in industrial applications like cutting tools and electronics. Its ability to withstand high temperatures and conduct electricity efficiently makes it valuable in manufacturing advanced electronic devices. For investors, companies working with silicon carbide are seen as key players in the growing market for high-performance electronics and energy-efficient technologies.

sic technical

"feature Vishay’s latest generation silicon carbide (SiC) MOSFETs in the industry-standard"

Sic is a short notation placed immediately after a quoted word or passage to show the text is reproduced exactly as it appeared in the original source, even if it contains a typo, odd phrasing, or factual error. For investors, it signals that any mistake or unusual wording came from the original speaker or document, not from the publisher—like an editor saying “this is how it was said,” which helps with accuracy, responsibility, and legal clarity.

mosfet technical

"introduced five new 1200 V MOSFET power modules designed to increase power efficiency"

A MOSFET is a tiny electronic switch used to control the flow of electricity in chips and circuits, functioning like a faucet that turns current on or off and adjusts how much passes through. Investors watch MOSFETs because their performance, cost and availability affect product power efficiency, manufacturing yields and supply chains for industries from consumer electronics to electric vehicles, which in turn can influence companies’ margins and growth prospects.

sot-227 technical

"MOSFETs in the industry-standard SOT-227 package. Offered in single switch"

An investigational drug candidate identified by the internal code “sot-227,” used by researchers and companies to track a specific compound through laboratory studies and clinical trials. For investors, such a code signals a potential future product whose clinical results, regulatory approvals, or safety issues can significantly change a company’s valuation—think of it as a prototype being tested; positive test results can boost prospects, while failures create downside risk.

rohs-compliant regulatory

"The RoHS-compliant devices deliver high speed switching with low capacitance"

RoHS-compliant means a product meets rules that limit or ban certain hazardous chemicals in electrical and electronic equipment, ensuring the item does not contain those restricted substances above set limits. For investors this matters because compliance affects a company's ability to sell in regulated markets, avoid fines and recalls, and manage production costs and supply-chain risks—similar to a food product following a recipe that omits banned ingredients to stay sellable and safe.

dc/dc converters technical

"for solar inverters; off-board chargers for electric vehicles (EV); SMPS, DC/DC converters, UPS"

A dc/dc converter is an electronic device that changes one direct-current voltage level to another—raising or lowering the voltage so electronic components and batteries get the right power. For investors, its efficiency, size and reliability matter because better converters improve product battery life, reduce heat and material costs, and can make devices more competitive, affecting manufacturing costs, margins and market adoption.
