IXYS Corporation (IXYS), incorporated on April 4, 1995, is a multi-market integrated semiconductor company. The Company is engaged in the development, manufacture and marketing of power semiconductors, mixed-signal integrated circuits (ICs), application specific integrated circuits (ASICs), microcontrollers, systems and radio frequency (RF) power semiconductors. Its power semiconductor products are divided into two primary categories: power metal-oxide-silicon (MOS) and power bipolar products. Its IC's include microcontrollers, solid-state relays (SSRs), line card access switch (LCAS) and data access arrangements (DAA) integrated products, application specific integrated circuits, and power management and control ICs. The Company's power semiconductors are used primarily to control electricity in power conversion systems, including uninterruptible power supplies (UPS) and switch-mode power supplies (SMPS), for applications, such as communications infrastructure, including wireless base stations, network servers and telecommunication switching stations; motor drives for industrial applications, such as industrial transportation, robotics, automation and process control equipment; medical electronics for applications, such as defibrillators and magnetic resonance imaging (MRI) equipment, and renewable energy sources, such as wind turbines and solar systems.

The Company designs and sells ICs that have applications in appliances, telecommunications, display, power management and security systems. Its microcontroller semiconductor products are designed for a range of applications, including consumer electronics, home appliances and security systems. Its mixed-signal ICs are used in telecommunications products, central office switching equipment, customer premises equipment, set top boxes, remote meter reading equipment, security systems, flat displays, medical electronics and defense aerospace systems. Its systems include laser diode drivers, high voltage pulse generators and modulators, and high power subsystems (stacks) that are based on its high power semiconductor devices. It also designs and sells RF power semiconductors that switch electricity at the high rates required by circuitry that generates radio frequencies. Its RF power devices are used in wireless infrastructure, industrial RF applications, medical systems and defense and space electronics. The Company designs its power semiconductor, IC and systems and RF semiconductor products primarily for industrial and business applications.

Power Semiconductors

The Company's power semiconductors are sold separately and are also packaged in high power modules that consist of multiple semiconductor dies. The Company's power MOS transistors operate at greater switching speeds than bipolar transistors. The Company's power MOS transistors consist of power metal-oxide-silicon field-effect transistor (MOSFETs) and insulated-gate bipolar transistors (IGBTs). A power MOSFET is a switch controlled by voltage at the gate. Power MOSFETs are used in combination with passive components to vary the amperage and frequency of electricity by switching on and off at high frequency. The Company's power MOSFETs are used primarily in power conversion systems and are focused on higher voltage applications ranging from 40 to 4,500 volts. IGBTs also are used as switches. The Company has developed IGBTs for high voltage applications. Its products are focused on voltage applications ranging from 40 volts to 4,500 volts. The Company's IGBTs are used as switches. Its products are focused on voltage applications ranging from 300 volts to 4,500 volts. Its IGBTs are used principally in alternating current (AC) motor drives, power systems and defibrillators.

The Company's bipolar products are also used to process electricity, but are activated by current rather than voltage. The Company's bipolar products consist of rectifiers and thyristors. Rectifiers convert AC power to direct current (DC) power and are used primarily in input and output rectification and inverters. The Company's rectifiers are used in DC and AC motor drives, power supplies, lighting and heating controls and welding equipment. A subset of the Company's rectifier product group is fast recovery epitaxial diodes (FRED), which are used principally in AC motor drives and power supplies. Thyristors are switches that can be turned on by a controlled signal and turned off only when the output current is reduced to zero, which occurs in the flow of AC power. Its thyristors are used in motor drives, defibrillators, power supplies, lighting and heating controls.

Integrated Circuits

The Company's ICs address the demand for analog, mixed-signal and digital interface solutions in communication and other industries and include microcontrollers, mixed-signal application-specific ICs. A microcontroller is a computer-on-a-chip that is optimized to control electronic devices, such as motors and user interfaces on appliances. A microcontroller includes a central processing unit, non-volatile program memory, random access memory for data storage and various peripheral capabilities. The Company's ZigBee wireless microcontrollers offer system-on-a-chip (SoC) solutions for home automation, smart energy and remote sensors. The Company manufactures SSRs that isolate the low current communication signal from the higher power circuit, while also switching to control the flow of current. The Company's SSRs, which include high voltage analog components, optocouplers and integrated packages, are utilized principally in telecommunication, and video and data communication applications, as well as instrumentation, industrial control and aerospace and automotive applications. A line card access switch (LCAS) is a solid-state solution for a switching function traditionally performed by electromagnetic devices. The Company's LCAS products are used in central office switching applications to enable data and voice telephony. Data access arrangements (DAAs) integrate various discrete components and are used in analog data communications that interface with telephone network applications. The Company's Litelink products are DAAs for applications, such as voice-over Internet protocol, wired communication lines and set top boxes. The Company designs high voltage, analog and mixed-signal ASICs for a range of applications. It also makes and sells power management and control ICs, such as current regulators, motion controllers, digital power modulators and drivers for power MOSFETs and IGBTs.

Radio Frequency Power Semiconductors

The Company's RF power devices switch electricity at the high rates necessary to enable the amplification or reception of radio frequencies. Its products include field-effect transistors (FETs), pseudomorphic-high-electron-mobility transistors (PHEMTs), Gunn diodes and monolithic microwave integrated circuits (MMICs).

Systems and Other Products

The Company manufactures and sells laser diode drivers, high voltage pulse generators and modulators. It also manufactures and sells high power subsystems, sometimes known as modules or stacks, which are principally based on high power semiconductor devices.

The Company competes with Fairchild Semiconductor, Fuji, Hitachi, Infineon, Microsemi, Mitsubishi, On Semiconductor, Powerex, Renesas Electronics, Semikron International, STMicroelectronics, Toshiba, Vishay Intertechnology, Atmel, Cypress Semiconductor, Freescale Semiconductor, Microchip, NEC, Renesas Electronics, Silicon Labs, Microsemi and Qorvo.
