SemiQ adds S7 package option to QSiC 1200V power module family
SemiQ Inc of Lake Forest, CA, USA — which designs, develops and manufactures silicon carbide (SiC) power semiconductors and 150mm SiC epitaxial wafers for high-voltage applications — has added an S7 package to its QSiC family of 1200V, half-bridge MOSFET and Schottky diode SiC power modules. The new products further enhance design flexibility by providing compact, high-efficiency, high-performance options for new designs while supporting drop-in-replacement in legacy systems that require more efficient operation.
The additions see the availability of a 529A MOSFET module (GCMX003A120S7B1), a 348A MOSFET module (GCMX005A120S7B1), and two low-noise SiC Schottky diode half-bridge modules (GHXS300A120S7D5 and GHXS400A120S7D5) in an S7 package with industry-standard 62mm footprints and a height of just 17mm.
The new package addresses the size, weight and power requirements of demanding applications ranging from induction heaters, welding equipment and uninterruptible power supplies (UPS) to photovoltaic and wind inverters, energy storage systems, high-voltage DC–DC converters and battery charging systems for electric vehicles (EVs). As well as the compact form factor of the modules themselves, high-efficiency, low-loss operation helps to reduce system heat dissipation and supports the use of smaller heatsinks.
“Our aim is to provide a comprehensive portfolio of SiC technologies that allow designers to optimize the efficiency, performance and size of today’s demanding applications,” says president Dr Timothy Han. “Adding new package option to our 1200V QSiC MOSFET and SiC diode module families further extends the choices available to designers who need to create completely new applications or who are looking to upgrade legacy systems without significant redesign.”
Crafted from high-performance ceramics, SemiQ’s modules are claimed to achieve exceptional performance levels and support increased power density and more compact designs, especially in high-frequency and high-power environments.
To guarantee a stable gate threshold voltage and premium gate oxide quality for each module, SemiQ conducts gate burn-in testing at the wafer level. In addition to the burn-in test, which contributes to mitigating extrinsic failure rates, various stress tests – including gate stress, high-temperature reverse bias (HTRB) drain stress, and high-humidity, high-voltage, high-temperature (H3TRB) – are employed to attain the necessary automotive- and industrial-grade quality standards. All parts have undergone testing surpassing 1400V.
