MOSFET (Si/SiC) Forum Discussions

This  is taken from the https://application-notes.digchip.com/070/70-41484.pdf link.As per the datasheet on page number 8 it is mentioned that fall time is 58nsec but i am getting 34nsec the calculation is uploaded in below picture. On page number 9  two -point representation of the gate-drain capacitance is shown and from the graph it can be seen that Udd=14V and on the same page Vdd=32V.So do i have to take Udd=14V or 32V. Calculation for fall time

Hi

I use a 2ED4820-EM in combination with 2 IAUC70N08S5N074 MOSFETS in a back2back common source configuration.

I have the following setup:

VBat is connected to a Power Supply with 31V / 11A.  I can switch on and off resistive load without any issues (IL =1A).

After I connected a DC-fan to channel A, the fan would start, but I couldnt stop it anymore and after that the output path is constantly on.

Attached you find the startup of the fan when connected directly to the power supply. Peak current is about 11A, once running it is using about 1A.

I also noticed, that even if no power (VBAT nor VDD) is present, the back2back MOSFETS are always conducting.

I suppose the 2ED4820 is still running fine. Question is, why are the MOSFETS broken? I guess they should be able to handle that amount of peak current. Or do I exceed the ratings in some way?

Cheers

Going through the data sheet, it is unclear to me what the Rds_on value will be when Vgs is 3.3V. I am attempting to activate a very wide range of loads (0.015W - 2000W+ [never exceeding 80A]) statically, with only a Raspberry Pi or standard Arduino Uno. Knowing the Rds_on will help me design a board properly, and if needed add a heat sink to the BOM. Thank you in advance.

I am looking for evaluation board to switch 48V DC resistive load with 10A max current to quickly test in lab, please let me know if i can order anything, switching frequency is on the higher side.

To whom it may concern,

About IRFG6110,

Does this product have different packaging depending on the manufacturing date?

When I searched, it seems that there are MO-036AB CIC and MO-036AB FET on the packaging.

Please advise.
