I just did a google search and got this supplier. This compound is electrically conductive. I would be careful. Very seldom have I used a conductive thermal compounds. I would check conductivity between the lead and the device. And for sure, I would check conductivity after I installed the Diodes and Mosfets. ________________________________ From: EV <[email protected]> on behalf of Jay Summet via EV <[email protected]> Sent: Monday, February 27, 2017 6:13 PM To: [email protected] Subject: Re: [EVDL] Silicon heat sink grease That depends upon your application. Between the controller's outside and the base plate, I agree with you. However, I'm using this between the MOSFETS and DIODES and the interior heatsync, which also doubles as one of the power rails. The circuit is designed such that the mosfets and diode cases must be electrically connected to the heatsync. (The heatsync is electrically isolated from the case by a SiPad.) So I'm looking specifically for something that will conduct electricity AND heat. (The MOSFET's and DIODES are connected via a screw, which will conduct electricity, but I figure the lower the resistance the better.) The carbon grease is electrically and thermally conductive, but it appears to be designed for switch contacts more than simiconductor heatsync applications, and is probably not as conductive as a silver grease, so I'm still poking around looking at what my options are to purchase.
