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.

SemiQ Inc has begun shipping its SiC MOSFET modules for integration into advanced cell cycling systems used by several of the world’s leading battery manufacturers.
In lithium-ion batteries, cell cyclers enable the formation of a stable solid electrolyte interphase to enable increased longevity and performance. The systems also enable battery manufacturers to perform battery degradation analysis, temperature and stress testing, and check for defects or performance issues.
To undertake these tasks, the cyclers need to accurately charge and discharge batteries, with high switching frequencies enabling more precise control of current and voltage to avoid damage from overcharging/discharging. For this function, the MOSFETs need to withstand the thermal stress of repeated power cycling, with failure leading to test disruption and inaccurate data. Conversion efficiency is also vital in minimizing operational costs.
SemiQ is supplying its GCMX003A120S3B1-N and the GCMX003A120S7B1 QSiC™ 1200 V SiC half-bridge modules for use in 100 kW cyclers (10 x 10 kW cells with parallel connections).
These high-speed switching MOSFET modules are highly efficient with exceptionally low switching losses, are designed with a reliable body diode, have been tested to over 1350 V and implement a rugged design with easy mounting. Each 10 kW cell will integrate 12 modules, with 120 per 100 kW per cycler.
Dr. Timothy Han, President at SemiQ said: “Reports show that the electrification of transportation is among the most important steps that can be taken to reach net-zero. For this, the evaluation of battery performance, durability, and efficiency plays a vital role in enabling the development of longer-range, longer-life EV batteries. We’re delighted to be working with one of the world’s leading cell cyclers and this partnership is testament to the ruggedness and efficiency of our SiC technology.”
Datasheets for the GCMX003A120S3B1-N and GCMX003A120S7B1 modules can be downloaded via the product page, here.
