Can any of gate driver IC packages be immersed under dielectric liquid (transformer oil)?

Getssy prathiba

Hello,

I am working on an application where in I am trying to study the switching characteristics of IGBT under dielectric liquid ( example: Transformer oil) at high voltage. I see different packages when I try to choose gate driver IC from TI for the IGBT. Could you please let me know if any of the package could be immersed in the liquid?

Best Regards,

Hi Getssy,

Any package should be fine as long as the dielectric oil is held at atmospheric pressure.

In fact, we do this to test the capacitive isolation inside our devices to prevent surface and/or air arcing.

For example, it's mentioned in the following two documents:

Dear Don,

Thank you for your concern. We have planned to use transformer oil.

Could you let me know if it can create any issues with the epoxy mold compound?

Best Regards,

Hi Getssy,

Can you provide trade name and/or formulation of the transformer oil?
