CISSOID offers support to customers replacing Honeywell's obsoleted High Temperature Microelectronics Products

Cissoid is the leader in High temperature
& Extended lifetime semiconductors

Since 2000, 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 -55C to +225C and commonly used outside that range, from cryogenic lows to upper extremes.

We provide solutions for


The ever increasing demand on the Automotive industry to drive down car emissions is a challenge and is driving the Manufacturers to look for ever increasing innovative solutions to meet these goals. The semiconductor content continues to increase but is now being located in more hostile location such as engine blocks, gear boxes and exhaust systems. Each of these require solutions that can operate at higher temperatures while maintaining the required lifetime reliability.
