SemiQ Unveils High-Performance QSiC™ Power Modules in Half-Bridge Packages

Dec 13, 2023 | Media

New 1200V SiC MOSFET modules deliver reliable, high-efficiency operation in photovoltaic inverter, battery charger, energy storage and high-voltage DC-DC converter applications.

December 13, 2023, Lake Forest, CA – SemiQ Inc, a designer, developer, and global supplier of superior SiC solutions for ultra-efficient, high-performance, and high-voltage applications, has expanded its QSiC™ power modules portfolio with the introduction of a new series of 1200V silicon-carbide (SiC) power MOSFETs in half-bridge packages.

Engineered and tested to operate reliably in demanding environments, these new compact, high-performance modules enable high-power-density implementations while minimizing dynamic and static losses. Featuring high breakdown voltage (>1400V), the new QSiC™ modules support high-temperature operation (Tj = 175°C) with low Rds(On) shift over the full temperature range. In addition, the modules exhibit industry-leading gate oxide stability and long gate oxide lifetime, avalanche unclamped inductive switching (UIS) ruggedness and long short-circuit withstand time.

With a solid foundation of high-performance ceramics, the new SiC modules are suitable for EV charging, on-board chargers (OBCs), DC-DC converters, E-compressors, fuel cell converters, medical power supplies, photovoltaic inverters, energy storage systems, solar and wind energy systems, data center power supplies, UPS/PFC circuits, Vienna rectifiers, and other automotive and industrial applications.

To ensure that each module has a stable gate threshold voltage and high-quality gate oxide, SemiQ’s modules undergo gate burn-in testing at the wafer level. Besides the burn-in test, which helps to stabilize the extrinsic failure rate, stress tests such as gate stress, high-temperature reverse bias (HTRB) drain stress, and high humidity, high voltage, high temperature (H3TRB) allow achieving the required automotive and industrial grade quality levels. The devices also have extended short-circuit ratings. All modules have undergone testing exceeding 1350V.

Dr. Timothy Han, President at SemiQ, said, “SemiQ’s commitment to reliability and testing sets us apart in the semiconductor industry. Our high-performance QSiC™ 1200V MOSFET modules are proven to withstand challenging conditions, enabling engineers to develop reliable systems for the renewable, automotive, medical, and industrial sectors.”

SemiQ’s new 1200V 5mΩ, 10mΩ, and 20mΩ SiC MOSFET are available in industry standard half-bridge packages. A table with part numbers is shown below.
