Infineon vs Vishay Mosfet Selection Help

[Botvink]

Hello friends,

For my design I am in difficulty for selecting the best mosfet for 100V range, I am paralelling and eliminated all to 2 model:
IAUMN10S5N016GAUMA1 - Infineon Technologies
https://www.infineon.com/assets/row/public/documents/10/49/infineon-iaumn10s5n016g-datasheet-en.pdf

And
SQJQ112E-T1_GE3 - Vishay
https://www.vishay.com/docs/79384/sqjq112e.pdf

Both are 100V and have similar current ratings, 296A vs. 310A. Vishay is a bit more affordable, but I don't know if it falls behind Infineon in quality or if there are any other significant differences. What do you think?

Are you using these in a motor controller? Haven't used the Vishay part, but have used OptiMOS 5 parts before in motor controller designs to great effect.

In my opinion, I'd only consider Vishay Siliconix parts in high(er)-power designs prone to (unintended) operation in avalanche if low cost were the overriding concern. For various power designs, I mostly have had better luck with OptiMOS parts. Sad what Siliconix has become in recent decades...

Very valuable reply, thank you.

Yes , I planned to order for my bldc driver.

For 500 pcs Vishay price is 2 usd, Infineon is 2.8 usd. But sure if one board fails under load and fast reverses, there will be no justifiying cost..

Both of those mosfets have fairly comparable specs.

largest difference I can see, the Infineon has an Rds(on)~1.6mΩ, while the Vishay has an Rds(on)~2.5mΩ.
That is enough on resistance difference to pick the Infineon part, if the price/performance is worth it to you.

Another thing to check is parasitic turn-on, this is calculated by dividing the Input capacitance(Ciss) by the Reverse transfer capacitance(Crss).
Both parts have a ratio over ~140, so, given operation in the ~80 volt range(20% headroom for 100 volts), should be fine.

Reference;
MP2-ESC

This thread is a wealth of info;
Modular, Multi-Platform, 300A ESC

Cheers!

While characteristics are close pick the one which has better reputation.
