Microsemi Corporation engages in the design, manufacture, and marketing of analog and mixed-signal integrated circuits (IC) and semiconductors primarily in the United States, Europe, and Asia. Its products include radio frequency (RF) and power components, analog and RF integrated circuits (IC), standard and customizable system-on-chip solutions, and mixed-signal and radiation-tolerant field programmable gate arrays. The company also offers subsystems and modules that include application-specific power modules and Power-over-Ethernet midspans. Its individual component semiconductor products include silicon rectifiers, zener diodes, low leakage and high voltage diodes, temperature compensated zener diodes, transistors, subminiature high power transient suppressor diodes, and pin diodes used in magnetic resonance imaging (MRI) machines. The company also manufactures semiconductors for commercial applications, such as automatic surge protectors, transient suppressor diodes used for telephone applications, and switching diodes used in computer systems. It primarily serves defense and security, aerospace, communications, and industrial and medical industries. The company’s IC products are used in data storage, wireless local area network, automobiles, telecommunications, test instruments, defense and aerospace equipment, high-quality sound reproduction, and data transfer equipment. It markets its products directly, as well as through electronic component distributors and independent sales representatives, as well as sales personal. The company was formerly known as Microsemiconductor Corporation and changed its name to Microsemi Corporation in February 1983. Microsemi Corporation was founded in 1960 and is headquartered in Aliso Viejo, California.
