CISSOID is the leader in high temperature semiconductor solutions, delivering standard products and custom solutions for power management, power conversion and signal conditioning in extreme temperature and harsh environments. CISSOID provides high reliability products guaranteed from -55°C to +225°C and commonly used outside that range, from cryogenic lows to upper extremes. Whether the ambient temperature is low but the power dissipation heats up the chips, or in high temperature environments, CISSOID products enable energy, weight and cost savings in lighter, cooling-free and more compact electronic systems. They are used in mission-critical systems as well as in applications requiring long term reliability. CISSOID supplies leaders in the Oil&Gas, Aeronautics, Industrial and Automotive markets.


The portfolio of High Temperature standard electronic components from CISSOID includes DC-DC converters reference designs, electric motor drivers solutions, Voltage Regulators, Voltage References, Clock Generators & Timers, Analog-to-Digital Converters, Amplifiers, Power MOSFET's and Drivers. Custom solutions can also be developed as an Application Specific Monolithic IC (ASIC) or as a Hybrid multichip assembly solution.


The outstanding reliability of CISSOID products comes from 25 years of experience in development and manufacturing of high temperature, high reliability semiconductor products. From design to simulation, from wafer process to assembly techniques, from characterization to thousands of hours life tests, CISSOID products benefit from the sharpest know-how in every step of the manufacturing flow targeting extreme temperature applications in harsh environment. High temperature semiconductor is our core business.
