Infineon Ramps Up Volume Production of CoolSiC MOSFET

Infineon Technologies enters high volume production of a comprehensive portfolio of 1200 V CoolSiC MOSFET devices. The devices are rated from 30 mΩ to 350 mΩ and implemented into TO247-3 and TO247-4 housings. The expansion includes a soon-to-be-launched surface mount device (SMD) portfolio and a 650 V CoolSiC MOSFET product family.

Infineon Ramps Up Volume

With these products, Infineon addresses the fast-growing demand for energy-efficient SiC solutions in power conversion schemes such as battery charging infrastructure, energy storage solutions, photovoltaic inverters, uninterruptable power supplies (UPS), motor drives as well as server and telecom switched-mode-power supplies (SMPS).

“At Infineon, the launch of a new base technology is subject to strict quality criteria,” said Peter Wawer, Division President Industrial Power Control at Infineon. “Production flows for high volume manufacturing must be proven, for front- and backend even when assembling discrete housings. This includes the collection of statistical data, production monitoring, and application-relevant testing beyond standardized procedures.”

Like Infineon’s previously launched CoolSiC MOSFET lead products in TO247 and Easy power module package, the new discrete devices build on a leading trench SiC MOSFET semiconductor process.

CoolSiC trench technology features an exclusively high threshold voltage rating (Vth) larger than 4 V combined with a low Miller capacitance. For this reason, CoolSiC MOSFETs exhibit best-in-class immunity against unwanted parasitic turn-on effects compared to other SiC MOSFETs on the market. Together with a turn-on gate-source voltage of +18 V with 5 V margin to maximum rated voltage of +23 V, the new Infineon SiC discrete MOSFETs deliver an advantage over silicon (Si) IGBTs, super-junction MOSFETs as well as over other SiC MOSFETs at highest level.

Including a robust body diode rated for hard commutation, the CoolSiC MOSFET portfolio gives engineers a pathway for highest energy efficiency and making “more out of less”. MOSFET functionality in SiC material offers a new degree of system design flexibility in power factor correction (PFC) circuits, bi-directional topologies and any hard and soft switching DC-DC converters or DC-AC inverters.

Infineon completes its discrete offering with a range of selected driver IC products fulfilling the needs posed by the ultrafast SiC MOSFET switching feature. Together, CoolSiC MOSFETs and EiceDRIVER gate driver ICs leverage the advantage of the technology: improved efficiency, space and weight savings, part count reduction, enhanced system reliability. Together, this opens up the possibility to lower system cost, reduces operational expenses and total cost of ownership, enabling new solutions in an energy-smart world.

“After the production ramp of the silicon carbide (SiC) MOSFET base technology has been safely completed, we are now bringing the most comprehensive discrete SiC portfolio for industrial applications to the market“ added, Peter Wawer.


The new 1200 V CoolSiC MOSFETs in TO247 package can be ordered now with a standard delivery lead-time. Corresponding on-resistance ratings in an SMD portfolio in D2PAK-7 housing will be available as engineering samples in Q4 2019. The 650 V CoolSiC MOSFET engineering samples in TO247-3 and TO247-4 rated at 26 mΩ to 107 mΩ will also become available in Q4 2019.
