New power SiC transistor and diode assemblies CHT-EUROPA and CHT-PLUTO from CISSOID
CISSOID, the leader in high temperature semiconductor solutions, extends its family of high temperature Silicon Carbide (SiC) power modules dedicated to power conversion and motor drive applications: CHT-PLUTO SiC MOSFET modules and CHT-EUROPA SiC Schottky diodes modules are rated for operation between -55°C and +225°C.
Today, 7 new power modules are introduced with different current ratings and topologies offering optimal trade-off between performance and cost:
1200V/30A Dual SiC MOSFET Module with freewheeling Schottky diodes
1200V/20A Dual SiC MOSFET Module with freewheeling Schottky diodes (new)
1200V/30A Dual SiC MOSFET Module (new)
1200V/20A Dual SiC MOSFET Module (new)
1200V/30A Buck or Boost Module: 1 SiC MOSFET + 1 SiC Schottky Diode (new)
1200V/20A Buck or Boost Module: 1 SiC MOSFET + 1 SiC Schottky Diode (new)
1200V/30A Dual SiC Schottky Diode Module (new)
1200V/20A Dual SiC Schottky Diode Module (new)
CHT-PLUTO and CHT-EUROPA power modules are available in hermetically sealed 8 pins proprietary “HM8A” metal package with dimensions of 18mm x 29mm excluding mounting tabs. The devices are electrically isolated from the case of the package. These new components benefit from CISSOID long experience in the manufacturing, packaging, testing and qualifying of high temperature semiconductors.
Depending on the converter (DC-DC/AC-DC/DC-AC, isolated/non-isolated, step-up/stepdown), the user can choose between different topologies: dual SiC MOSFET, with or without embedded freewheeling SiC Schottky diode; Buck or Boost configuration featuring independent SiC MOSFET and SiC Schottky Diode; or a dual SiC Schottky diode. CHTPLUTO and CHT-EUROPA modules allow designers to address current ratings from 20A up to 60A, using 2 devices of a single module in parallel. Selecting the right current rating offers the optimal trade-off between conduction and switching losses as well as the right cost for the application.
The On-resistance and thermal resistance of CHT-PLUTO SiC MOSFET modules directly scale with the current rating, respectively from 90mOhms down to 23mOhms at VGS=20V and from 1.2°C/W down to 0.35°C/W. This allows for the optimal selection of the module rating depending on total losses and the temperature mission profile of the power converter. The high operating junction temperature, up to 225°C, and the low switching energies of SiC MOSFET’s, which are lower than 600µJ at 20A, offers further design headroom. All the modules are rated with a breakdown voltage in excess of 1200V at 225°C.
With two additional source connectors for an easy and robust connection to the gate driver, CHT-PLUTO MOSFET modules are ideally controlled by CISSOID new high temperature gate driver, HADES® v2, featuring high peak current capability and its high dV/dT robustness, enabling very fast switching and low switching losses. Dave Hutton, CEO at CISSOID, said: “The extension of CHT-PLUTO family shows our ongoing commitment to delivering high temperature semiconductor solutions for power conversion and motor drives applications. This paves the way of SiC MOSFET Intelligent Power Modules (IPM’s), including both the power devices and the gate drivers, which are currently in development by CISSOID. Switching currents in excess of 150A, these IPM’s will address the needs for high power density and high reliability in Industrial, Aerospace, Transportation and EV/HEV markets.”
