content: Hi All,Looking for a source for a HZIP25 compatible off-the-shelf heatsink (datasheet of part with this kind of package attached).Surely Digikey must have it (they have 100k+ type of heatsinks in their portfolio), but for the life of me, I cannot find the HZIP option in the "package cooled" filter. Can anyone help me on this one? I would prefer Digikey as a supplier because I am working on a project with single supplier (Digikey) to save shipping costs.Regards,Cristian

content: I would think you could get better response if you gave some links , picture etc. , having a few large boxes of heat sinks , I am not going to do a search on your part number to find a match ?

content: Hi,thanks for looking into this. I have added in the first post an image of the package and detailed dimensions (hope they are visible, the pdf datasheet I took the screenshot from is rather poor quality)Regards,Cristian

content: Hay Cristian ,Well that is the part your trying to cool , what about the part your looking for , I am guessing that could vary - depending on how hard your going to use the device ?Would you be able to use something that fits the part , but maybe mod the mount , drill & tap ?With out the drawing of the heat sink , not way to know dimensions , how it is mounted etc.

content: Ah, I see what you mean. Well, I was hoping there are standard heatsinks for this type of package.There is only one way you can really mount the component on the PCB (straight through holes for each pin), and any heatsink would work if it were purposely built for this type of package. But in fairness, I kind of gave up hope to find a specially made one (like there are tones of for TO220, for instance). I eventually found some 3$ heatsink on Digikey that would be close enough, which I can drill and screw against the back of the package.Regards,Cristian

content: I could probably match the size and you would probably need to drill & tap , for free , but shipping from US would cost more that what you may get locally ?

content: Yes, of course, that would not be very efficient, thanks for considering it anyway.My initial question was more aimed to finding out if there is any off-the shelf HZIP25 packagededicatedheatsink available at one of the major component distributors. I am planning to get all my components from Digikey for this project and I will get the 7-340-2PP-BA heatsink for this part. It is not dedicated to it, but with some drilling it will work.Regards,Cristian
