SemiQ Inc has broadened its third-generation QSiC™ MOSFET portfolio with seven new power modules that deliver industry-leading current density and thermal performance. The launch adds high-current S3 half-bridge, B2T1 six-pack and B3 full-bridge options engineered to raise system efficiency, simplify cooling, and cut switching losses in next-generation EV chargers, energy storage systems and industrial motor drives.
The expanded lineup targets the rising demand for ultra-efficient power conversion. In the standard 62 mm S3 half-bridge format, current capability reaches up to 608 A with junction-to-case thermal resistance as low as 0.07°C/W. The B2T1 six-pack modules integrate a complete three-phase power stage in a compact housing with RDS(on) values from 19.5 to 82 mΩ to streamline layout and minimize parasitics in motor drives and advanced AC-DC converters. The B3 full-bridge devices offer up to 120 A with on-resistance down to 8.6 mΩ and thermal resistance of 0.28°C/W, maximizing power density and efficiency for single-phase inverters and high-voltage DC-DC applications.
Quality and reliability measures include wafer-level gate-oxide burn-in to assure gate integrity and breakdown voltage testing beyond 1350 V. Built on SemiQ’s Gen3 SiC technology, the new modules operate at 18 V/-4.5 V gate drive and reduce both RONsp and turn-off energy (EOFF) by up to 30% versus prior generations.
Commenting on the release, Dr. Timothy Han said that EV infrastructure and new industrial applications demand ever-higher performance, and that the Gen3 full-bridge, half-bridge and six-pack modules—with higher current density and significantly lower on-resistance—are designed to meet those requirements.

ROHM has commenced mass production of its SCT40xxDLL series silicon carbide (SiC) MOSFETs in TO-Leadless (TOLL) packages, offering a significant 39% improvement in thermal performance compared to conventional TO-263-7L packages with equivalent voltage ratings and on-resistance. The new series is designed to meet the growing demand for compact, high-power components in applications such as AI server power supplies and energy storage systems (ESS), where power density and miniaturization are increasingly critical.
As modern industrial and consumer equipment evolves, applications such as compact photovoltaic (PV) inverters and high-efficiency server systems face dual requirements: increasing power capability and reduced system size. This is especially true for power factor correction (PFC) circuits in slim-profile “pizza box” server power supplies, where discrete semiconductors must conform to strict thickness constraints of 4 mm or less.
ROHM’s SCT40xxDLL series responds to these requirements with a compact 2.3 mm low-profile form factor—approximately 50% thinner than traditional equivalents—and a reduced component footprint by about 26%. The series also distinguishes itself with a rated drain-source voltage of up to 750 V, surpassing the standard 650 V found in many TOLL package MOSFETs. This higher voltage rating contributes to increased surge voltage tolerance, lower gate resistance requirements, and reduced switching losses.
The SCT40xxDLL lineup includes six models with typical on-resistance values ranging from 13 mΩ to 65 mΩ. Maximum current ratings span up to 120 A, depending on the device, making them suitable for a wide range of high-performance power conversion systems. Mass production began in September 2025.
SCT40xxDLL Series Overview:
Part Number VDSS Max (V) RDS(on) Typ (mΩ) ID Max (A) PD Max (W) Storage Temp (°C) SCT4013DLL 750 13 120 405 -40 to +175 SCT4020DLL 750 20 80 277 -40 to +175 SCT4026DLL 750 26 61 214 -40 to +175 SCT4036DLL 750 36 46 164 -40 to +175 SCT4045DLL 750 45 37 133 -40 to +175 SCT4065DLL 750 65 26 100 -40 to +175 These devices are suitable for use in:
- Industrial power supplies for AI servers and data centers
- Photovoltaic inverters and ESS
- General-purpose consumer power supply applications
ROHM also provides simulation models for all six variants via its official website to assist engineers with rapid circuit evaluation and design. The SCT40xxDLL series is available through authorized distributors.

Vishay Intertechnology, Inc. has announced the release of two new 1200 V silicon carbide (SiC) MOSFET power modules designed to enhance efficiency and system reliability in automotive, industrial, energy, and telecommunications applications. The new modules, designated VS-MPY038P120 and VS-MPX075P120, integrate advanced SiC technology in a low-profile MAACPAK PressFit package and are aimed at supporting medium to high frequency operations.
Each module combines Vishay’s latest generation of SiC MOSFETs with an NTC thermistor for integrated temperature sensing and fast intrinsic SiC diodes for minimized reverse recovery. These features result in reduced switching losses and higher efficiency in a range of demanding applications, including electric and hybrid vehicle chargers, solar inverters, motor drives, UPS systems, HVAC systems, large-scale energy storage, and telecom power supplies.
The rugged transfer mold construction of the new modules contributes to longer operational lifespans compared to traditional designs, while offering improved thermal resistance. Their compact, low-profile package design minimizes parasitic inductance and electromagnetic interference (EMI), and helps conserve board space. In addition, the PressFit pin layout follows established industry standards, facilitating drop-in replacement for existing solutions with enhanced electrical performance.
The VS-MPY038P120 features a full-bridge inverter topology, an on-resistance of 38 mΩ, and a continuous drain current of 35 A at 80 °C. The VS-MPX075P120 adopts a three-phase inverter topology, with an on-resistance of 75 mΩ and a continuous drain current of 18 A. Both modules support high-speed switching, offer low capacitance, and operate at junction temperatures up to 175 °C. They are RoHS-compliant and halogen-free.
Samples and production volumes for the VS-MPX075P120 and VS-MPY038P120 are currently available, with standard lead times of 13 weeks.

GaN / LATEST NEWS / WBG2 Min Read
The U.S. International Trade Commission (ITC) has issued a preliminary ruling finding that Innoscience has violated one of the gallium nitride (GaN) technology patents held by Infineon Technologies AG. The ITC also confirmed the legal validity of both patents asserted by Infineon in the case.
The dispute centers on Innoscience’s alleged unauthorized use of Infineon’s patented GaN technologies. A final determination by the ITC is expected on April 2, 2026. Should the preliminary ruling be upheld, it will result in an import ban of the allegedly infringing Innoscience products into the United States.
“This ruling is another testament to the strength of Infineon’s intellectual property and confirms our commitment to vigorously defend our patent portfolio against infringements and ensuring fair competition in the market,” said Johannes Schoiswohl, Senior Vice President and Head of Infineon’s GaN Systems Business Line. “We remain dedicated to fostering innovation and advancing semiconductor technology to address the world’s most pressing challenges, from decarbonization to digital transformation.”
The decision in the U.S. adds to a series of favorable outcomes for Infineon in similar disputes. In a separate case in Germany, the German patent office recently upheld the validity of an Infineon GaN patent in a slightly amended form, and Infineon is pursuing infringement claims related to that patent in the Munich District Court. Additionally, in August 2025, the Munich District Court I ruled that another Infineon GaN patent had been infringed by Innoscience.
Infineon is a leading integrated device manufacturer in the GaN market and holds one of the industry’s most extensive intellectual property portfolios, with approximately 450 GaN patent families. GaN is a critical technology for high-performance, energy-efficient power systems used in applications ranging from renewable energy and AI data centers to industrial automation and electric vehicles.
By mastering all three essential materials in power electronics—silicon (Si), silicon carbide (SiC), and gallium nitride (GaN)—Infineon continues to play a pivotal role in advancing semiconductor innovation to support the global push for energy efficiency and sustainability.
