Infineon has entered high volume production of a comprehensive portfolio of 1200 V CoolSiC mosfet devices.
They are rated from 30 mO to 350 mO and implemented into TO247-3 and TO247-4 housings.
The expansion includes a surface mount device (SMD) portfolio and a 650 V CoolSiC mosfet product family, both to be launched soon.
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).
As for all 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.
This process was developed to allow for both lowest losses in the application and highest reliability in operation.
Furthermore, according to related application profiles, gate-source operating voltages are adopted for discrete package solutions. A benchmark low dynamic loss enables highest efficiency with a simple unipolar gate drive scheme.
CoolSiC trench technology features an exclusively high threshold voltage rating (Vth) larger than 4V 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 mosfets 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.
The 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 D 2PAK-7 housing will be available as engineering samples in Q4 2019. The 650 V CoolSiC mosfets engineering samples in TO247-3 and TO247-4 rated at 26 mO to 107 mO will also become available in Q4 2019.
