I am looking for a MOSFET device which has the fastest tdon and tr time, the BVDSS>=800V, ID>=1A. I do not care other parameters. I only found one manufactured by Microsemi, the part# is: APT4M120K, its tdon=7.4ns, tr=4.4ns. Do you guys know other faster MOSFETs.
I am developing a circuit...
If some of you who know a reliable bare die source (IGBT and fast recovery diode), could you please let me know. Many thanks. I have contacted with Mintech, ditech, semidice, they seemed not willing to do business with us since our company is not a large company.
