Folks:
After a frustrating hour in Fry's, I can not find extra Silipad insulators for my TO-3p mosfet's.
I did find some "CPU Thermal tape" which is for sticking a CPU to a heat sink. There's no grounding issues there, so I don't know if this will inslulate or not. It will be a mounting method (no bolts) as well as good thermal condutivity.
Do you think I can use the CPU tape for my amp?

Hi,
Silverloaded thermal paste works fine too.
And I do believe the P stands for Plastic Casing.

Thermal resistance vs voltage rating
Watch the thermal resistance on some of those silpad type materials. The ones with a high voltage rating (often used for SMPS's etc) have pretty ordinary thermal performance. Also, the thinner the pad/tape is, the flatter your surfaces have to be.
I think TO3-P is like TO-247 but with a bit of the metal tab exposed around the top edge, also the mounting hole is not insulated like in the '47.

Right, like a TO-247; here's a picture:
Exicon 10N20
The non insulated is the big issue, it HAS to be isolated from the heat sink, or I'll be frying bacon instead of listning to music!
I don't see how thermal paste will help do that.
Where can I get some Silipad's? I couldn't find any at Mouser

😱 Well, it's off to DigiKey then!
UPS is getting 1/2 of my project cost, one minimum charge at a time 🙄 lol
Thanks folks, this forum is great.

24 pads hit me for the 5 dollar handling fee, so I ordered 40.
I plan on bi-amping in the future, so I just ordered enough for all 10 of my amps. I have all the passive's too, same theory.

I agree its tough one to answer ..
But I go with Adhesive tapes.. why because the other thing wont go much competitive in this case.. And when my cars had the problem, I used it .. got the result.

Thanks for the suggestion of the adhesive tape, Mr. Adhesive tape salesman.
I think they got it all sorted a little over 7 years ago though.
