Based on volume experience and compatibility know-how, Infineon introduces the revolutionary CoolSiC™ MOSFET technology which enables radically new product designs. In comparison to traditional Silicon based switches like IGBTs and MOSFETs, the Silicon Carbide (SiC) MOSFET offers a series of advantages. CoolSiC™ MOSFET products in 1700 V, 1200 V and 650 V target photovoltaic inverters, battery charging. energy storage, motor drives, UPS, auxiliary power supplies and SMPS. Silicon Carbide CoolSiC™ MOSFET represents the best performance, reliability and ease of use for system designers. Silicon Carbide (SiC) opens up new degrees of flexibility for designers to harness never before seen levels of efficiency and reliability.
Enhancing new materials to offer customers extended levels of performance
CoolSiC™ MOSFET offers a series of advantages. These include, the lowest gate charge and device capacitance levels seen in SiC switches, no reverse recovery losses of the anti-parallel diode, temperature independent low switching losses, and threshold-free on-state characteristics.
Infineon’s unique CoolSiC™ MOSFET adds additional advantages. Superior gate oxide reliability enabled by state-of-the-art trench design, best in class switching and conduction losses, highest transconductance level (gain), threshold voltage of Vth = 4V and short-circuit robustness. This is the revolution you can rely on.
All this results in a robust Silicon Carbide MOSFET, ideal for hard- and resonant-switching topologies like LLC and ZVS, which can be driven like an IGBT or MOSFET with easy to use drivers. Delivering the highest level efficiency at high switching frequencies allowing for system size reduction, power density increases and high lifetime reliability.
Product line up
CoolSiC™ MOSFET first products in different housings
TO-247-4pin package contains an additional connection to the source (Kelvin connection) that is used as a reference potential for the gate driving voltage, thereby eliminating the effect of voltage drops over the source inductance. The result is even lower switching losses than for TO247-3pin version, especially at higher currents and higher switching frequencies. CoolSiC™ MOSFET Easy modules offer a very good thermal interface, a low stray inductance and robust design as well as PressFIT connections. While low power ranges can be ideally addressed with the Easy family, medium power inverters of 250+ kW can best make use of the 62mm package.
