Solitron Devices announced the introduction of the SD11487, the industry’s first hermetically sealed Silicon Carbide (SiC) Power Module for high reliability applications.
With a unique hermetic packaging format, the 51mm x 30mm x 8mm outline is the smallest hermetically sealed high reliability, high voltage, half-bridge on the market. The integrated format maximizes power density while minimizing loop inductance. 60 mil pins for the power output stage are isolated on one side of the package to allow simple power bussing while 30 mil pins are on the opposite side for control signals.
The SD11487 is a half bridge configuration with two 1200V 12mΩ SiC MOSFETs. Also included in the module are two freewheeling 1200V SiC Schottky diodes in parallel with the MOSFETs and an integrated NTC temperature sensor. Continuous drain current is specified at 95A.
With operating temperatures of -55°C to 175°C, the SD11487 is designed for the most demanding applications such as down hole exploration; space; and avionics. The hermetically sealed copper package combined with the Alumina Nitride direct bond copper substrate provide excellent thermal conductivity as well as case isolation. The integrated temperature sensing enables high level temperature protection.
Silicon Carbide provides excellent switching performance versus the best-in-class silicon MOSFETs and IGBTs with minimal variation versus temperature. Higher efficiency levels than silicon due to significantly lower energy loss and reverse charge results in more switching power and less energy required in the switch-on and switch-off phase. Combined with high switching frequencies this translates to smaller magnetics significantly reducing system weight and size.

Nexperia announced its first silicon carbide (SiC) MOSFETs with the release of two 1200 V discrete devices in 3-pin TO-247 packaging with RDS(on) values of 40 mΩ and 80 mΩ. NSF040120L3A0 and NSF080120L3A0 are the first in a series of planned releases which will see Nexperia’s SiC MOSFET portfolio quickly expand to include devices with a variety of RDS(on) values in a choice of through-hole and surface mounted packages.
This release addresses the market demand for the increased availability of high performance SiC MOSFETs in industrial applications including electric vehicle (EV) charging piles, uninterruptible power supplies (UPS) and inverters for solar and energy storage systems (ESS).
“With these inaugural products, Nexperia and Mitsubishi Electric wanted to bring true innovation to a market that has been crying out for more wide-bandgap device suppliers”, according to Katrin Feurle, Senior Director & Head of Product Group SiC at Nexperia. “Nexperia can now offer SiC MOSFET devices which offer best-in-class performance across several parameters, including high RDS(on) temperature stability, low body diode voltage drop, tight threshold voltage specification as well as a very well-balanced gate charge ratio making the device safe against parasitic turn on. This is the opening chapter in our commitment to producing the highest quality SiC MOSFETs in our partnership with Mitsubishi Electric. Together we will undoubtedly push the boundaries of SiC device performance over the coming years”.
“Together with Nexperia, we’re thrilled to introduce these new SiC MOSFETs as the first product of our partnership”, says Toru Iwagami, Senior General Manger, Power Device Works, Semiconductor & Device Group in Mitsubishi Electric. “Mitsubishi Electric has accumulated superior expertise of SiC power semiconductors, and our devices deliver a unique balance of characteristics.”
RDS(on) is a critical performance parameter for SiC MOSFETs as it impacts conduction power losses. Nexperia identified this as a limiting factor in the performance of many currently available SiC devices and used its innovative process technology to ensure its new SiC MOSFETs offer industry-leading temperature stability, with the nominal value of RDS(on) increasing by only 38% over an operating temperature range from 25°C to 175°C. Unlike other many currently available SiC devices in the market.
Nexperia’s SiC MOSFETs also exhibit the very low total gate charge (QG), which brings the advantage of lower gate drive losses. Furthermore, Nexperia balanced gate charge to have an exceptionally low ratio of QGD to QGS, a characteristic which increases device immunity against parasitic turn-on.
Together with the positive temperature coefficient of SiC MOSFETs, Nexperia’s SiC MOSFETs offers also ultra-low spread in device-to device threshold voltage, VGS(th), which allows very well-balanced current-carrying performance under static and dynamic conditions when devices are operated in parallel. Furthermore, low body diode forward voltage (VSD) is a parameter which increases device robustness and efficiency, while also relaxing the dead-time requirement for asynchronous rectification and free wheel operation.
Nexperia is also planning the future release of automotive grade MOSFETs. The NSF040120L3A0 and NSF080120L3A0 are available in production quantities now. Please contact Nexperia sales representatives for samples of the full SiC MOSFET offering.
