I don't know this insulating sheet under the IGBT. Does it have a professional name?

Isn't the thermal conductive silicone sheet silver-gray? What's the difference between this golden yellow one and the other?

Gray is more common, but there are also red and beige ones.
Placed under IGBT and MOS tubes, they are mainly for heat conduction, insulation, sealing, non-deformation, corrosion resistance, etc.

The photo shows the bottom of the IGBT, with AC input, so the withstand voltage is probably enough.

Thank you.

Silicone cloth costs 10 yuan per square meter. It is a three-layer structure of double-sided silicone and fiber cloth, which is easy to identify.

The price of Teflon insulation sheet starts from 10 times, and it can be as thin as 0.1mm, with lower thermal resistance

This is a borrowed device that was blown up. I bought it on Taobao according to the color for 180 yuan. When I come back and look at the size, I should know what it is.
