Consider a part like Digikey 596-1809-ND. It has an eSip-7C package. I can butt a TO-220 heatsink up against it, but this is poor. Can anyone recommend a better and available heatsink? It must be mechanically sound, preferably independently mounted to the PCB. I need some kind of clamping action. I will consider any range of thermal characteristics.
I would also consider a metal clip that screws to a standard TO-220 heatsink. This is basically what Power Integrations suggests, but they are vague on specifics. And they suggest plastic, which seems like a bad idea to me. I can easily design this, but I am getting unrealistic quotes. And I will purchase 10,000 of them.
Thanks. MLA
