Where can I buy a thin heatsink?

[hithesh123]

I need a thin heatsink, like the sheet metal heat sink used in SMPS.
But I can't find them on digikey.
Is it called by a different name?
Where can I buy it.

Re: Heatsink

Not that. I saw that on digikey. It's expensive.
The one I am talking about is for a TO-220 package. Its just a plain sheet of aluminum bolted to the chip.

Something like this:

https://www.newark.com/wakefield-th...opular Heat Sinks&MER=PPSO_N_P_HeatSinks_None

Hope this helps.

There are 1492 heatsink on Digikey.

What exactly can you not find? What thermal resistance do you need?

This one is cheap, but you do need to say what thermal resistance you want.

This is what I am talking about(see attachment). The folded Aluminum sheet attached to the TO220.

That may not be a catalog item, it's really just bent sheet
metal (or flat stock). Which you could replicate easily enough
with stock from any hardware store, and hand tools, in minutes.
