New Cissoid Products


CISSOID has introduced CXT family of components designed and qualified for high-temperature automotive environments with operating junction temperature from -55°C up to +175°C (Tj), in excess of AEC-Q100 Grade 0 qualification standard: A 50mA adjustable linear voltage regulator and configurable devices enabling 13 logic functions.


Gate Driver boards optimized for 62mm Silicon Carbide (SiC) MOSFET Power Modules rated at 125°C (Ta) and offering thermal headroom for the design of high density power converters in automotive and industrial applications. They enable high frequency (>100KHz) and fast SiC MOSFET's switching (dV/dt>50KV/µs), improving efficiency and reducing size and weight of the power converters.


High Temperature High Voltage Silicon Carbide (SiC) MOSFET transistor, available in standard TO-247 package and guaranteed from -55°C to +175°C (Tj). The device has a breakdown voltage in excess of 1200V and can switch currents up to 60A.


CISSOID has introduced a new platform of SiC MOSFETs Intelligent Power Modules designed for automotive and industrial electrical motor drives. This new platform enables high power density converters giving access to the full benefits of SiC technology thanks to operation at high junction temperature (up to 175°C) and low switching losses.
