Who is Cissoid?

CISSOID are leaders in high-temperature semiconductor solutions, delivering standard products and custom solutions in extreme temperature and harsh environments. These solutions include:

  • Power Management
  • Power Conversion
  • Signal Conditioning

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, these 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 products are supplied to a number of leaders in the Oil & Gas, Aeronautics, Industrial and Automotive markets

Please be advised that due to the ongoing supply issues with raw materials affecting the global electronics industry, as well as an increase in orders received by our manufacturing partners, a large number of products are facing increased lead times in recent months. For the latest lead time and stock availability, please contact one of our engineers who will be happy to discuss lead times further and the potential for alternative parts.
