Powerex Inc., is a Pennsylvania-based company specializing in high power semiconductor applications. Powerex supports many markets, including transportation, AC and DC motor controls, UPS, alternative energy, medical power supplies, welding, industrial heating, electrical vehicles, aircraft and communications.
Established on January 1, 1986, Powerex inc. was the result of cooperation between two major players in the power semiconductor industry -- the Power Semiconductor Divisions of General Electric Company and Westinghouse Electric Corporation. Mitsubishi Electric Corporation later established an equity position in Powerex. In 1994, Westinghouse sold its shares to General Electric and Mitsubishi Electric, the present equal majority shareholders. Corporate offices and manufacturing facilities are located in western Pennsylvania.
Powerex offers a broad line of products, including IGBTs, mosfets, thyristors, rectifiers, diodes, fast recovery diodes, DC-DC converters, and assemblies.

A diode is a two-terminal electronic component that conducts current primarily in one direction ; it has low resistance in one direction, and high resistance in the other.
The Mitsubishi Group is a group of autonomous Japanese multinational companies in a variety of industries.
Toshiba Corporation is a Japanese multinational conglomerate headquartered in Minato, Tokyo. Its diversified products and services include power, industrial and social infrastructure systems, elevators and escalators, electronic components, semiconductors, hard disk drives (HDD), printers, batteries, lighting, as well as IT solutions such as quantum cryptography which has been in development at Cambridge Research Laboratory, Toshiba Europe, located in the United Kingdom, now being commercialised. It was one of the biggest manufacturers of personal computers, consumer electronics, home appliances, and medical equipment. As a semiconductor company and the inventor of flash memory, Toshiba had been one of the top 10 in the chip industry until its flash memory unit was spun off as Toshiba Memory, later Kioxia, in the late 2010s.

The Westinghouse Electric Corporation was an American manufacturing company founded in 1886 by George Westinghouse. It was originally named "Westinghouse Electric & Manufacturing Company", and was renamed "Westinghouse Electric Corporation" in 1945. The company acquired the CBS television network in 1995, and was renamed as the first incarnation of "CBS Corporation", until being acquired by Viacom in 1999. That merger was completed on April 26, 2000.
Westinghouse Electric Company LLC is an American nuclear power company formed in 1999 from the nuclear power division of the original Westinghouse Electric Corporation. It offers nuclear products and services to utilities internationally, including nuclear fuel, service and maintenance, instrumentation, control and design of nuclear power plants. Westinghouse's world headquarters are located in the Pittsburgh suburb of Cranberry Township, Pennsylvania. Brookfield Business Partners is the majority owner of Westinghouse.
Renesas Electronics Corporation is a Japanese semiconductor manufacturer headquartered in Tokyo, Japan, initially incorporated in 2002 as Renesas Technology, the consolidated entity of the semiconductor units of Hitachi and Mitsubishi excluding their dynamic random-access memory businesses, to which NEC Electronics merged in 2010, resulting in a minor change in the corporate name and logo to as it is now.
Mitsubishi Electric Corporation, established on 15 January 1921, is a Japanese multinational electronics and electrical equipment manufacturing company headquartered in Tokyo, Japan. It is one of the core companies of Mitsubishi. The products from MELCO include elevators and escalators, high-end home appliances, air conditioning, factory automation systems, train systems, electric motors, pumps, semiconductors, digital signage, and satellites.
The Westinghouse Astronuclear Laboratory (WANL) was a division of Westinghouse Electric Corporation. Established in 1959 to develop nuclear space propulsion technologies for the government, the lab was located, for most of its history, in the paradoxically small town of "Large" along Pa. Rte 51, about 13 miles (21 km) south of Pittsburgh in Allegheny County, Pennsylvania, USA. The site is not far from the Bettis Atomic Power Laboratory in West Mifflin, which Westinghouse operated during the same time and later.
onsemi is an American semiconductor supplier company, one of the Fortune 500. Products include power and signal management, logic, discrete, and custom devices for automotive, communications, computing, consumer, industrial, LED lighting, medical, military/aerospace and power applications. onsemi runs a network of manufacturing facilities, sales offices and design centers in North America, Europe, and the Asia Pacific regions. Headquartered in Phoenix, Arizona, onsemi has revenues of $3.907 billion (2016), which puts it among the worldwide top 20 semiconductor sales leaders.
A LED display is a flat panel display that uses an array of light-emitting diodes as pixels for a video display. Their brightness allows them to be used outdoors where they are visible in the sun for store signs and billboards. In recent years, they have also become commonly used in destination signs on public transport vehicles, as well as variable-message signs on highways. LED displays are capable of providing general illumination in addition to visual display, as when used for stage lighting or other decorative purposes. LED displays can offer higher contrast ratios than a projector and are thus an alternative to traditional projection screens, and they can be used for large, uninterrupted video walls. microLED displays are LED displays with smaller LEDs, which poses significant development challenges.
Microsemi Corporation was an Aliso Viejo, California-based provider of semiconductor and system solutions for aerospace & defense, communications, data center and industrial markets.
SUMCO Corporation is a Japanese semiconductor company, manufacturing silicon wafers for semiconductor manufacturers worldwide. The company was established in 1999 as a joint venture between Mitsubishi Materials Corporation and Sumitomo Metal Industries and as of 2013 is the second largest silicon wafer producer in the world, after Shin-Etsu Handotai, with a market share of 30%.
Mitsubishi Electric United States is the principal subsidiary of Mitsubishi Electric Corporation in the United States. It is headquartered in Cypress, California and was incorporated in 2002 and its affiliates, have roughly 31 locations throughout North America with approximately 5,000 employees. Its main affiliate companies are: Mitsubishi Electric Power Products, Inc.; Mitsubishi Electric US, Inc.; Mitsubishi Electric Automotive America, Inc.; Mitsubishi Electric Automation, Inc.; and Mitsubishi Electric Research Laboratories, Inc.
T. P. "Peter" Brody was a British-naturalised physicist and the co-inventor of Active Matrix Thin-Film Transistor display technology together with Fang-Chen Luo, having produced the world's first Active Matrix Liquid Crystal Display (AM-LCD) in 1972 and the first functional AM-EL in 1973 while employed by Westinghouse Electric Corporation in Pittsburgh. Brody coined the term "active matrix" and first used it in a published journal article in 1975.
IXYS Corporation is an American company based in Milpitas, California. IXYS focuses on power semiconductors, radio-frequency (RF) power semiconductors, and digital and analog integrated circuits (ICs).
Shindengen Electric Manufacturing is a Japanese, Tokyo-based company, manufacturing power semiconductor devices, electric power systems, automotive electronics products and solenoid products. It is listed on the Tokyo Stock Exchange and the company's largest shareholder is Honda.
Transitron Electronic Corporation was a semiconductor device fabrication company of the United States. It was founded by Leo and David Bakalar incorporated in Wakefield, Massachusetts, in 1952. David Bakalar was the president from 1952 to 1984. In 1986 the company went out of business, failing to keep pace with the rapid advances in technology.
