heatsinks for SOT-23

they actually do make heatsinks for TO-92 though and just why
-F

like look at this ridiculous looking thing

i almost want to find an excuse to use one just for how absurd it looks
-F

also it has an absurdly bad thermal resistance but what do you expect for something that just goes on top of a to-92 like a hat

it's rated for 60°C/W with natural convection, and 17.5°C/W with 400 LFM forced air flow

-F

like if this heatsink is going to be enough for your purposes you can probably get an equivalent device in a TO-220 package and just not use a heatsink at all

@Felthry

I was thinking the same, but maybe if you're /that/ desperate for board space? O.o;

@Felthry I was thinking looking at it ... like, we were studying heat transfer in grad school, looking specifically at electronic packaging

there are, like, so many layers creating thermal resistance between the heat-generating element and the heat sink in that design ... it's kinda impressive that they managed to make it better than nothing

@packbat i guess almost anything would be better than nothing unless you use like styrofoam or something but yeah, there's... no way you should ever be using TO-92 if you need any sort of heat transfer

Even the metal version, TO-18, has pretty awful thermal properties
