Hi The devices all *worked* just fine, even without any heatsink at all. There was no performance impact to the (lack of) heatsink in a normal lab environment.
Small in this case is mounting the device to a heatsink that is the size of the “hot” side and maybe a half inch of fins. Fins always get oriented to be vertical. Again, the only issue is reliability. Bob > On Oct 20, 2020, at 11:08 PM, Hal Murray <[email protected]> wrote: > > >> I spent a lot of years buying Rb’s and putting them on small heatsinks.
