Hello,

I am working on an application where in I am trying to study the switching characteristics of IGBT under dielectric liquid at high voltage.
Could you please let me know TO- 247 packaged IGBTs could be immersed in the liquid?

I could not find the exact chemical composition. But I could find the trade names. There are two oils which are used as follows.

1)shell diala s4 zx-i (mineral oil - http://tdc.ge/wp-content/uploads/201...la_S4_ZX-I.pdf)

2) MIDEL 7131 - Synthetic Ester Transformer Fluid ( https://www.midel.com/app/uploads/20...t-Brochure.pdf

Best Regards,
Getssy
