Markets and Technology

In applications from 20 W to 20 MW, and with device voltages from 650 V to 6.5 kV, GeneSiC silicon carbide (SiC) MOSFETs and Schottky MPS™ diodes drive high-speed, high-efficiency power conversion across diverse markets including EV, industrial automation, solar, wind, grid, motor drives and defense. High-volume, high-quality shipments ensure application performance, reliability and uptime availability. 

Trench-Assisted Planar Gate: No-Compromise Technology

SiC MOSFETs offer superior conductivity and switching performance compared to silicon (Si) due to their ‘wide bandgap’ characteristics and high electric-field strength. However, traditional designs using legacy planar or trench techniques must compromise between manufacturability, performance, and/or reliability.

GeneSiC’s patented trench-assisted planar gate design is a no-compromise, next-generation solution; high-yield manufacturing, fast and cool operation, and extended, long-life reliability.

Cool. Fast.

Efficient, cost-effective power conversion relies on a comprehensive understanding of modern circuit topologies and high-speed (frequency) switching techniques. There are two main device factors:

• How well does the MOSFET conduct current (measured in RDS(ON) )?
• How efficiently does the device ‘switch’ (measured by energy loss, or EXX )?

For each question, we must understand the answer in both ‘hard-switch’ and ‘soft-switch’ topologies, and under tough high-temperature and high-speed conditions. Combined, a high-temperature, high-speed (frequency) figure-of-merit (FoM) is critical for system performance and reliability.

GeneSiC patented trench-assisted planar-gate technology delivers the lowest RDS(ON) at high temperature and the lowest energy losses at high speeds. This enables unprecedented, industry-leading levels of performance, robustness and quality.

Typical Circuits

650 V MPS™ Diodes

GeneSiC’s new 5th-generation 650 V Merged-PiN Schottky (MPS™) diodes integrate a unique PiN Schottky structure, delivering ‘Low-Built-In Voltage-Biasing’ (“low knee”) for highest efficiency across all load conditions with superior robustness. Applications include PFC in server/telecom power supplies, industrial motor drives, solar inverters, LCD/LED TVs, and lighting.

Merged-PiN Schottky (MPS™) with Low-Built-In Voltage-Biasing Technology

A novel GeneSiC Merged-PiN Schottky design combines the best features from both PiN and Schottky diode structures, producing the lowest forward voltage drop (VF), high surge-current capability (IFSM), and minimized temperature-independent switching losses. Proprietary thin-chip technology further reduces VF and improves thermal dissipation for cooler operation.

Superior Figure-of-Merit (FoM) Drives High Efficiency

Gen-5 MPS Diodes are ideal in PFC circuits in continuous-current mode (CCM) due to excellent figure of merit, comprising of a low VF of 1.3 V, minimized capacitive charge (QC). In addition, zero reverse recovery charge improves PFC MOSFET turn-on performance. The result is a cooler, more reliable system.

3 kW Interleaved Boost PFC

Built to the Highest Level of Reliability

Gen-5, 650 V MPS Diodes offer best-in-class robustness and ruggedness for applications demanding high surge current and avalanche capability, critical for fail-safe designs. All GeneSiC devices are 100% avalanche (UIL) production tested to ensure the highest level of ruggedness in over-voltage conditions.

High Power Modules & Die Sales

GeneSiC SiCPAK™ modules and bare-die enable expanded applications ranging from 10s kW to MW in rail, EV, fast charging, industry, solar, wind and energy storage.

GeneSiC SiCPAK™ modules have been designed for superior performance and robustness, while meeting industry-standard press-fit footprint with pin-to-pin compatibility.

GeneSiC MOSFET and diode technologies range from 650 V to 6500 V using trench-assisted planar gate technology, to provide lowest RDS(ON) positive temperature coefficient to enable highest efficiency at real operating temperatures. Die has been optimized for different bonding and attach styles with various metallizations including aluminum and gold.

SiC Schottky MPS™ Diodes

Merged-PiN Schottky (MPS) diodes combine two beneficial features from the PIN and Schottky diode. The PIN sustains excessive surge currents with low leakage, while the Schottky element offers low forward voltage drop and fast-switching characteristics. Target applications include PFC, boost, and high-voltage, higher-power motor drives.

Electrify Our World™

In May 2022, Navitas announced that it was the world’s first semiconductor company to achieve CarbonNeutral®-company certification, another milestone towards Navitas’ mission to “Electrify Our World” and to help Navitas’ customers achieve their own sustainability goals.

Silicon Carbide technology enables CO2 reduction by increasing system efficiency and through ‘dematerialization’ – using less case material, heatsink, PCBs, etc. vs. legacy silicon IGBTs.

Each KATEK coolcept fleX Steca solar inverter uses 16x GeneSiC G3R75MT12J SiC MOSFETs per 4.6 kW unit. The 1,200 V, 75 mΩ-rated devices are used in a two-level converter, with bi-directional boost converters and an H4-topology for AC voltage output. Increased switching frequency shrinks the size and weight.

“Next-generation GeneSiC technology has enabled a major step in system performance without compromising our high engineering standards, especially regarding EMI,” said Dr. Peter Grabs, KATEK’s Director of Innovation, Research and Development. “Navitas’ excellent quality – with zero failures – and consistent, short lead-time delivery are critical success factors as we expand production into new markets.”

Exide’s high frequency chargers convert 220 V AC power to a battery-level voltage between 24 and 80 V for lead-acid and lithium-ion battery-powered industrial vehicles. The 7 kW module uses GeneSiC G3R60MT07D (750 V) MOSFETs and GD10MPS12A (1,200 V) MPS Schottky diodes, with frequency-optimized architecture. The same platform can be upgraded to 10 kW, with 4 modules in parallel to provide 40 kW of reliable fast-charging power.

“Exide Technologies delivers complete, carefully controlled fast-charging with close system monitoring for critical material-handling equipment, running 24/7,” said Dr. Dominik Margraf, Director Product Management Motion at Exide Technologies. “Navitas’ GeneSiC technology is easy-to-use, with excellent support, increased system efficiency, and cooler operation.”
