Alpha and Omega Semiconductor Limited
Alpha and Omega Semiconductor Limited designs, develops, and supplies power semiconductor products for computing, consumer electronics, communication, and industrial applications in Hong Kong, China, South Korea, the United States, and internationally. The company offers power discrete products, including metal-oxide-semiconductor field-effect transistors (MOSFET), Shielded-Gate low voltage and mid-voltage MOSFETs, SuperJunction high voltage MOSFETs, and trench-stop insulated gate bipolar transistors (IGBTs), as well as application specific MOSFETs for use in smartphone chargers, battery packs, notebooks, desktop and servers, data centers, base stations, graphics card, game boxes, TVs, AC adapters, power supplies, motor control, power tools, e-vehicles, white goods and industrial motor drives, UPS systems, solar inverters, and industrial welding. It also provides power ICs that deliver power, as well as control and regulate the power management variables, such as the flow of current and level of voltage. The company's power ICs are used in flat panel displays, TVs, notebooks, graphic cards, servers, AI datacenters, DVD/Blu-Ray players, set-top boxes, and networking equipment. In addition, the company offers transient voltage protection products, analog switches, and electromagnetic interference filters for notebooks, desktop PCs, tablets, flat panel displays, TVs, smartphones, and portable electronic devices. Further, it provides silicon carbide, IPM, TVS, and HV gate drivers; and power modules, multiphase controllers, EZBuck regulators, and diode protection switches. Alpha and Omega Semiconductor Limited was incorporated in 2000 and is headquartered in Sunnyvale, California.

Vishay Intertechnology, Inc. manufactures and sells discrete semiconductors and passive electronic components in the United States, Germany, rest of Europe, Israel, and Asia. The company operates through six segments: Metal Oxide Semiconductor Field Effect Transistors (MOSFETs), Diodes, Optoelectronic Components, Resistors, Inductors, and Capacitors segments. The MOSFETs segment offers low- and medium-voltage TrenchFET MOSFETs, high-voltage planar MOSFETs, high voltage Super Junction MOSFETs, power integrated circuits, and integrated function power devices. The Diodes segment provides rectifiers, small signal diodes, protection diodes, thyristors/silicon-controlled rectifiers, and power modules. The Optoelectronic Components segment offers standard and customer specific optoelectronic components, such as infrared (IR) emitters and detectors, IR remote control receivers, optocouplers, solid-state relays, optical sensors, light-emitting diodes, 7-segment displays, and IR data transceiver modules. The Resistors segment provides resistors used in various forms of electronic circuitry to adjust and regulate levels of voltage and current. The Inductors segment provides inductors for use as an internal magnetic field to change alternating current phase and resist alternating current. The Capacitors segment offers capacitors that store energy and discharge. It sells its products under the Siliconix, Dale, Draloric, Beyschlag, Sfernice, MCB, UltraSource, Applied Thin-Film Products, IHLP, HiRel Systems, Sprague, Vitramon, Barry, Roederstein, ESTA, Ametherm, and BCcomponents brand names. The company serves industrial, automotive, telecommunications, computing, consumer products, power supplies, military and aerospace, and medical end markets. Vishay Intertechnology, Inc. was incorporated in 1962 and is headquartered in Malvern, Pennsylvania.
