MOSFET (Si/SiC) Forum Discussions
I am looking for the spice simulation model for the TDA21490 or something close to this one.
The purpose is to simulate a multiphase PSU using this MOS.
Thanks for any suggestion

I am currently looking for a PCB footprint of FF23MR12W1M1P_B11.I didn't find this package on Infineon's website.
Where can I find those?
Many thanks in advance!
where can I get Power MOSFET reliability data from Infinion?
The results I am getting from MIL217 prediction are rather poor and I think actual reliability may be better.Show Less
is there any source, where a table can be found, which contains the switching-frequency of the following Transistors?
GaN, SiC, Si, IGBT, ...
I was only able to find diagrams. E.g.:
SI/SIC MOSFETs all generate parasitic diodes through internal P+ - N- - N+ (PiN),
But why the reason for the lower Qrr of SIC MOSFET ?
Is it because the N-epitaxial layer of the SIC MOSFET is thinner (low resistivity), when the body diode is off, it can have a faster recombination effect, resulting in lower stored charge (Qrr)?
When the MOS transistor spw55n80c3 was opened, the rising speed of the driving waveform was slow. It took 400ns to stay at Maitreya platform, resulting in serious MOS transistor heating. The currently selected driving chip is mic4452, and the driving capacity can reach 12a. In addition, could you send some usage and driving routines of the MOS transistor spw55n80c3? Thank you very much
How to evaluate power device junction temperature, at the time of Eon?
For example, the power dissipation I see is about 6kW+2.3kW,
Is my temperature rise equal to TA + (6kW+2.3kW) *RJA?
