Infineon Technologies AG is a German semiconductor manufacturer founded in 1999, when the semiconductor operations of the former parent company Siemens AG were spun off. Infineon has about 46,700 employees and is a global top 10 semiconductor company. 

After several restructurings, Infineon today comprises four business areas: 

(1) Automotive (ATV)

We shape the future of mobility with microelectronics enabling clean, safe and smart cars.

Semiconductors are essential for supporting the automotive megatrends: electro-mobility, automated driving, connectivity and advanced security. Our products link the real and the digital world, driving the ever-advancing pace of automotive digitalization. We are the number one semiconductor partner in the fast-changing automotive world, based on our system knowledge and our passion for innovation and quality.

(2) Industrial Power Control (IPC)

We empower a world of unlimited energy

Power semiconductors play a crucial role in increasing efficiency and reducing energy losses along the whole energy conversion chain. As the global leader in power semiconductors, we deliver pioneering products and solutions for smart and efficient energy generation, transmission and consumption. We strive to make this planet a greener place where sufficient energy is accessible to everyone – wherever and whenever it is needed.

(3) Power & Sensor Systems (PSS)

We drive leading-edge power management, sensing and data transfer capabilities.

Semiconductors play a vital role in enabling intelligent power management, smart sensitivity as well as fast and reliable data processing in an increasingly digitalized world. Our leading-edge power and connectivity devices make chargers, servers, mainboards, power tools and lighting systems smarter, smaller, lighter and more energy-efficient. In addition, our trusted sensors give things an intuitive sensing capability to make them contextually aware, and our RF chips power fast and reliable data communications.

(4) Connected Secure Systems (CSS)

We deliver end-to-end systems for a connected, secured world.

In a connected world of endless possibilities, digital systems require computing, connectivity and security capabilities. We make life smarter, more intuitive and secure with our trusted, game-changing microcontrollers as well as our wireless and security solutions. In addition, we shape the future by securely linking the real and the digital world.

Important Events:

(1) Cypress is now Infineon

The integration of Cypress is a major step for Infineon and a unique opportunity for our customers. Its product range is a perfect match. We will offer the industry’s most comprehensive portfolio for linking the real with the digital world – comprising an unparalleled range of hardware, software and security solutions for the connected age. The acquisition makes Infineon one of the world's top 10 semiconductor manufacturers.

(2) Infineon and International Rectifier

This is a powerful combination and a unique opportunity for Infineon's customers. Both companies complement each other outstandingly in their distributional strengths, in their competitive products, and in their leading technological and innovative excellence. Infineon's customers therefore take advantage from:

Enhanced support

Expanded product portfolio

More advanced solutions

With great knowledge of specific customer needs and application know-how, International Rectifier will successfully contribute to Infineon’s strategic approach from product thinking to system understanding.
