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.

Based on its 2016 revenues of $3.907 billion, onsemi ranked among the worldwide top 20 semiconductor sales leaders, and was ranked No. 483 on the 2022 Fortune 500 based on its 2021 sales.
A LED display is a flat panel display that uses an array of light-emitting diodes (LEDs) 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.
Diodes Incorporated is a global manufacturer and supplier of application specific standard products within the discrete, logic, analog, and mixed-signal semiconductor markets. Diodes serves the consumer electronics, computing, communications, industrial, and automotive markets.
