STMicroelectronics announced a new high-volume 200mm silicon carbide (“SiC”) manufacturing facility for power devices and modules, as well as test and packaging, to be built in Catania, Italy. Combined with the SiC substrate manufacturing facility being readied on the same site, these facilities will form ST’s Silicon Carbide Campus, realizing the Company’s vision of a fully vertically integrated manufacturing facility for the mass production of SiC on one site.
The creation of the new Silicon Carbide Campus is a key milestone to support customers for SiC devices across automotive, industrial and cloud infrastructure applications, as they transition to electrification and seek higher efficiency.
“The fully integrated capabilities unlocked by the Silicon Carbide Campus in Catania will contribute significantly to ST’s SiC technology leadership for automotive and industrial customers through the next decades,” said Jean-Marc Chery, President and Chief Executive Officer of STMicroelectronics. “The scale and synergies offered by this project will enable us to better innovate with high-volume manufacturing capacity, to the benefit of our European and global customers as they transition to electrification and seek more energy efficient solutions to meet their decarbonization goals.”
The Silicon Carbide Campus will serve as the center of ST’s global SiC ecosystem, integrating all steps in the production flow, including SiC substrate development, epitaxial growth processes, 200mm front-end wafer fabrication and module back-end assembly, as well as process R&D, product design, advanced R&D labs for dies, power systems and modules, and full packaging capabilities. This will achieve a first of a kind in Europe for the mass production of 200mm SiC wafers with each step of the process – substrate, epitaxy & front-end, and back-end – using 200 mm technologies for enhanced yields and performances.
The new facility is targeted to start production in 2026 and to ramp to full capacity by 2033, with up to 15,000 wafers per week at full build-out. The total investment is expected to be around five billion euros, with a support of around two billion euros provided by the State of Italy within the framework of the EU Chips Act. Sustainable practices are integral to the design, development, and operation of the Silicon Carbide Campus to ensure the responsible consumption of resources including water and power.

STMicroelectronics unveiled L99H92 automotive gate driver which provides an SPI port for programming and diagnostics, a charge pump, protective features, and two additional current-sense amplifiers for system monitoring.
Containing two high-side and two low-side drivers, the L99H92 can control a single H-bridge powering one bidirectional DC motor or two half bridges for two unidirectional motors. Typical applications for the highly integrated and easily configurable driver include electric sunroof, window lift, powered trunk, sliding doors, and seat-belt pre-tensioners.
The charge pump powers the high-side drivers to maintain correct operation as the vehicle battery voltage fluctuates, enabling the outputs to function with a supply as low as 5.41V. The charge-pump output is also available at an external pin to control a MOSFET for reverse-battery protection.
The gate-driving current is programmed through the SPI port, allowing slew-rate control to minimize electromagnetic emissions and thermal dissipation. Programming the current saves up to four external discrete components per MOSFET, typically needed for slew-rate setting with conventional drivers. The maximum drive current of 170mA gives designers flexibility to use the driver with a wide variety of external MOSFETs, including high-power devices with large gate capacitance.
With many features for system protection and diagnostics, the L99H92 is built for reliability and safety. There is overcurrent protection with a programmable threshold, detected by monitoring the MOSFET drain current. Also, cross-conduction protection with programmable dead time ensures safety and efficiency. Additional protection includes overtemperature early warning and shutdown, overvoltage and undervoltage protection on analog and digital power supply inputs, and open-load and output short-circuit detection in off-state diagnostic mode.
A fail-safe input can turn off all MOSFETs instantaneously and a dedicated diagnostic pin provides immediate fault warning without waiting for periodic SPI transfers.
Additionally, two current-sense amplifiers are integrated for system-status monitoring, helping minimize the bill of materials. Suitable for high-side, low-side, and inline sensing, the amplifiers have independently programmable gain, low offset, and low thermal drift. They can be independently disabled to reduce current consumption when unused.

STMicroelectronics introduced 100V trench Schottky rectifier diodes that boost efficiency in power converters operated at high switching frequencies.
Raising power-converter operating frequency, encouraged by the minimal switching losses of technologies like wide-bandgap semiconductors, allows designers to set new benchmarks in power density. However, at elevated frequencies, the energy losses in conventional planar diodes, including silicon Schottky devices, used as rectifiers become a significant factor limiting conversion efficiency.
ST’s trench Schottky diodes significantly reduce the rectifier losses, with superior forward-voltage and reverse-recovery characteristics that enable increased power density with high efficiency. The forward voltage is 50-100mV better than in comparable planar diodes, depending on current and temperature conditions. Simply changing to these devices can increase the efficiency by 0.5%.
There are 28 variants in the new family, with eight current ratings from 1A to 15A, multiple surface-mount packages, in industrial and automotive grades. The industrial-grade parts target applications such as miniature switched-mode power supplies and auxiliary power supplies for telecom, server, and smart-metering equipment.
In automotive, typical uses include space-constrained applications such as LED lighting, reverse-polarity protection, and low-voltage DC/DC converters. The parts are AEC-Q101 qualified, manufactured in PPAP-capable facilities, and specified from -40°C to 175°C.
When combined with ST’s flyback and buck-boost converters, such as the VIPer controllers and HVLED001A offline LED driver, the 100V trench Schottky rectifiers fulfil the active-components bill of materials for switched-mode power supplies. All are supported in ST’s eDesign Suite Rectifier Diodes Simulator, which helps to select the rating and footprint, simulate waveforms, and estimate power efficiency.
The diodes are 100% avalanche tested in production to ensure device robustness and system reliability. They are available in DPAK as well as SOD123 Flat, SOD128 Flat, SMB Flat, and PSMC (TO227A) surface-mount packages.

STMicroelectronics released automotive-grade 600V/650V super-junction MOSFETs in STPOWER MDmesh DM9 AG series which deliver superior efficiency and ruggedness for on-board chargers (OBCs) and DC/DC converter applications in both hard- and soft-switching topologies.
With outstanding RDS(on) per die area and minimal gate charge, the silicon-based devices combine low energy losses with outstanding switching performance, setting a new benchmark figure of merit. Compared to the previous generation, the latest MDmesh DM9 technology ensures a tighter gate-source threshold voltage (VGS(th)) spread that results in sharper switching for lower turn-on and turn-off losses.
In addition, body-diode reverse recovery is improved, leveraging a new optimized process that also increases the MOSFETs’ overall ruggedness. The diode’s low reverse-recovery charge (Qrr) and fast recovery time (trr) make the MDmesh DM9 AG series ideal for phase-shift zero-voltage switching topologies that demand the utmost efficiency.
The family offers a selection of through-hole and surface-mount packages that help designers achieve a compact form factor with high power density and system reliability. The TO-247 LL (long-lead) is a popular through-hole option that eases design-in and leverages proven assembly processes. Among the surface-mount packages, the H2PAK-2 (2 leads) and H2PAK-7(7 leads) are optimized for bottom-side cooling with thermal substrates or PCBs featuring thermal vias or other enhancement. HU3PAK and ACEPACK™ SMIT topside-cooled surface-mount packages are also available.
The first device in the new STPOWER MDmesh DM9 AG series is the STH60N099DM9-2AG, a 27A AEC-Q101 qualified N-channel 600V device in H2PAK-2, with 76mΩ typical RDS(on). ST will expand the family to provide a full range of devices, covering a broad range of current ratings and RDS(on) from 23mΩ to 150mΩ.
