Navitas sampling 3300V and 2300V UHV silicon carbide product portfolio
Navitas Semiconductor Corp of Torrance, CA, USA — which provides GaNFast gallium nitride (GaN) and GeneSiC silicon carbide (SiC) power semiconductors — has announced the sample availability of its new 3300V and 2300V ultrahigh-voltage (UHV) products in power module, discrete and known good die (KGD) formats. The new SiC products are claimed to set a benchmark for reliability and enhanced performance in ultrahigh-voltage power electronics.
Proprietary Trench-Assisted Planar (TAP) SiC MOSFET technology augments performance and reliability
The 3300V and 2300V UHV devices are based on Navitas’ fourth-generation GeneSiC platform, which uses a TAP architecture to implement a multi-step e-field management profile that significantly reduces voltage stress and improves voltage blocking capabilities compared with trench and traditional-planar SiC MOSFETs.
This TAP architecture is therefore able to provide increased long-term reliability and avalanche robustness. Navitas’ TAP technology also features an optimal source contact for superior cell-pitch density and enhanced current spreading, which results in improved switching figures of merit and lower on-resistance at hot temperatures.
Innovative packaging maximizes system durability and power density
Navitas is hence expanding the 3300V and 2300V UHV SiC product portfolio in flexible packaging formats to meet diverse application requirements. For high-power-density and high-reliability systems, the products are integrated into an advanced SiCPAK G+ power module package, offered in half-bridge and full-bridge circuit configurations.
The SiCPAK G+ power modules feature a unique epoxy-resin potting technology, which has been proven to deliver a >60% improvement in power cycling lifetime and a >10x improvement in thermal shock reliability over similar silicone-gel potted power module technology.
Key features of the SiCPAK G+ power modules also include an AlN DBC substrate for superior heat dissipation and new high-current press-fit pins that double the current-carrying capability per pin. Discrete SiC MOSFETs are available in the industry standard TO-247 and TO-263-7 packages.
Extended reliability testing validates long-term system lifetime
Navitas has created what it claims is an industry-first reliability qualification benchmark, AEC-Plus, indicating that SiC products are qualified above and beyond the existing AEC-Q101 and JEDEC product qualification standards. Navitas says that this new benchmark shows its understanding of system-level lifetime requirements, and a strong commitment to enabling rigorously designed and validated products for demanding mission profiles in grid and energy infrastructure applications. The AEC-Plus grade qualification standards extend further into rigorous multi-lot testing and qualification. Key additions to the existing AEC-Q101 requirements include:
- dynamic reverse bias (DRB) and dynamic gate switching (DGS) to represent stringent fast-switching application mission profiles;
- over 3x longer duration for static high-temperature, high-voltage tests (HTRB, HTGB, HTGB-R);
- HV-THB qualification for power modules and HV-H3TRB qualification for discrete and KGD;
- longer power cycling and temperature cycling.
Advanced KGD screening enables more stringent production screening
Navitas’ latest-generation 3300V and 2300V SiC MOSFETs are also offered as KGD products, which gives system manufacturers greater flexibility in building custom SiC power modules. To deliver the highest quality for bare die products and SiCPAK G+ power module family, Navitas’ devices pass through an advanced production screening process. This includes comprehensive room and hot temperature testing on singulated die (post-dicing) and a 6-side optical inspection. This rigorous KGD screening protocol ensures that only thoroughly tested die are used, improving manufacturing quality and increasing the final module's performance and reliability for critical ultrahigh-voltage applications.
“Navitas’ new 3300V and 2300V SiC product portfolio allows our customers to push the boundaries of efficiency and reliability in solid-state transformers for AI data centers, as well as utility-scale battery energy storage and renewable energy to define a new standard for such mission-critical system applications,” says Paul Wheeler, VP & general manager of the SiC business unit.
“This line of reliable, high-performance ultrahigh-voltage power semiconductors is expected to be a significant step in our roadmap to 10kV SiC solutions,” he adds. “By combining our proprietary Trench-Assisted Planar SiC MOSFET technology with innovative power packages, we are able to extend reliability qualification and support more stringent production screening, to deliver industry-leading performance and robustness.”
