What sort of speed? You need to search distributors web sites, Avnet, DigiKey, Mouser etc (type in SiC MOSFET in the search bar), and not manufacturers data sheets, since there is no guarantee that parts will be in stock at present, lead times have spiralled out of control for many parts. Driving these things at high speed is not trivial, a dedicated SiC MOSFET gate driver is a must if you need speed, and you would need a high bandwidth scope if you are doing any sort of design work. You would need some knowledge of RF PCB layout, there will be application notes from SiC MOSFET and gate drivers manufacturers to help in that respect. To see how complex the problem could be, have a look at the information below. https://www.youtube.com/watch?v=BJBy1YIQeSg https://www.youtube.com/watch?v=j1sL_PaZpck Cheers, Richard
Just decided to drop an answer even when you haven't responded to my question.
There are several different models of SiC MOSFETs available on the market, and the fastest model will depend on the specific performance characteristics you are looking for. Some of the fastest SiC MOSFETs currently available include:
Cree C2M0025120D: This is a 1200V, 25mΩ SiC MOSFET with a switching frequency of up to 10 kHz.
Infineon BSM150GB120DN2: This is a 1200V, 15mΩ SiC MOSFET with a switching frequency of up to 20 kHz.
Rohm SCTH30N120S2G: This is a 1200V, 30mΩ SiC MOSFET with a switching frequency of up to 20 kHz.
Toshiba TK16A60W: This is a 600V, 16mΩ SiC MOSFET with a switching frequency of up to 50 kHz.
It is important to note that the switching frequency of a SiC MOSFET is not the only factor to consider when selecting a device. Other important factors include the device's on-resistance, voltage rating, and maximum operating temperature. You should carefully evaluate the available options and select a SiC MOSFET that meets your specific performance and application requirements.
