SemiQ Inc has announced a family of co-packaged 1200 V SOT-227 MOSFET modules based on its third-generation SiC technology.
In addition to smaller die sizes, third generation SIC devices offer faster switching speeds and reduced losses.
The family of highly rugged and easy mount devices currently offers six devices with an RDSon range of 8.4 to 39 mΩ: GCMS008C120S1-E1, GCMX008C120S1-E1, GCMS016C120S1-E1, GCMX016C120S1-E1, GCMS040C120S1-E1 and GCMX040C120S1-E1, with the GCMX040C120S1-E1 having a switching time as low as 67 ns. In addition to these six, two further modules – GCMS080C120S1-E1 and GCMX080C120S1-E1 – are available, each with an RDSon of 80 mΩ.
The COPACK MOSFETs with Schottky barrier diode provides exceptional switching losses at high junction temperature due to the low turn on switching losses.
SemiQ is targeting the robust SiC MOSFET modules at applications including solar inverters, energy storage systems, battery charging, and server power supplies. All devices have been screened with wafer-level gate-oxide burn-in tests and tested beyond 1400 V, with avalanche testing to 330 mJ (RDSon = 39 mΩ) or 800 mJ (RDSon = 16.5 or 8.4 mΩ).
In addition to having a drain-to-source voltage (VDS) of 1200 V, the MOSFET reduces total switching losses to as low as 468 µJ and a reverse recovery charge of 172 nC (GCMX040C120S1-E1). The family also has a low junction-to-case thermal resistance and comes with an isolated backplate and the ability to directly mount to a heatsink by 4kVAC galvanic isolation testing.
Specifications: Ratings and electrical/thermal characteristics
The QSiC 1200 V MOSFET modules have a continuous operational and storage temperature of -55oC to 175oC. It has a recommended operational gate-source voltage of -4.5/18 V, with a VGSmax of -8/22 V, and a power dissipation of 183 to 536 W (RDSon = 39 and mΩ, core and junction temperature 25oC).
For static electrical characteristics, the device has a junction-to-case thermal resistance of 0.23oC per watt (RDSon = 8.4) as well as a typical zero-gate voltage drain current of 100 nA, and a gate-source voltage current of 10 nA.
The fastest switching device has a turn-on delay time of 13 ns with a rise time of 7 ns; its turn-off delay time is 18 ns with a fall time of 29 ns.

SemiQ Launches High-Efficiency 1200V SiC MOSFET Six-Pack Modules for Scalable, Compact Power Designs
2 Min ReadSemiQ Inc has announced a series of highly efficient 1200 V SiC MOSFET Six-Pack Modules. These have been designed to enable lower cost and more compact system-level designs at large scale.
The rugged, high-speed switching SiC MOSFETs implement a planar technology with rugged gate oxide and feature a reliable body diode. These are arranged in a three-phase bridge topology, with the modules additionally featuring split DC negative terminals, press-fit terminal connections and a Kelvin reference for stable operation.
The high-power-density modules benefit from low switching losses, as well as low junction-to-case thermal resistance and all parts have been tested beyond 1350 V, with 100% wafer-level burn in (WLBI).
They have been developed for applications including AC/DC converters, energy storage systems, battery charging, motor drives and PFC boost converters, including EV fast charging, induction heating and welding, renewable energy supplies and UPS.
The modules are operational to 175oC junction temperature, and have been designed for easy mounting, including direct mounting to a heatsink. The product family has been launched with 20, 40 and 80mΩ variants (GCMX020A120B2T1P, GCMX040A120B2T1P, GCMX080A120B2T1P) that have a power dissipation of 263, 160 and 103 W respectively.

Diodes Incorporated announced the expansion of its silicon carbide (SiC) product portfolio with a series of five high-performance, low figure-of-merit (FOM) 650V SiC Schottky diodes. Rated at 4A, 6A, 8A, 10A, and 12A, the DSCxxA065LP series is housed in the ultra-thermally efficient T-DFN8080-4 package and is designed for high-efficiency power switching applications, such as DC to DC and AC to DC conversion, renewable energy, data centers (especially those that process heavy artificial intelligence (AI) workloads), and industrial motor drives.
The industry-leading FOM, calculated as FOM=QC×VF, is attributed to:
- Negligible switching losses, thanks to the absence of reverse recovery current and low capacitive charge (QC), and
- Low forward voltage (VF) minimizing conduction losses, enhancing overall power efficiency.
These characteristics make them ideal for high-speed switching circuits.
The high-performance SiC diodes are also notable for their lowest reverse leakage (IR) in the industry, at 20µA (max.). This minimizes heat dissipation and conduction losses, improving system stability and reliability, particularly in comparison to silicon Schottky devices. This reduction in heat dissipation also lowers cooling costs and operating expenses.
The compact and low-profile T-DFN8080-4 (typ. 8mm x 8mm x 1mm) surface mount package incorporates a large underside heat pad, which reduces thermal resistance. Requiring less board space and providing a larger heat pad, the T‑DFN8080-4 is an ideal alternative to the TO252 (DPAK). This benefits circuit designs by increasing power density, reducing overall solution size, and lowering the cooling budget.
The 4A DSC04A065LP, 6A DSC06A065LP, 8A DSC08A065LP, 10A DSC10A065LP, and 12A DSC12A065LP are available at $1.25, $1.55, $1.80, $2.10, and $2.40, respectively, each in 2,500-piece quantities.
