this collet type heat sink is only made for testing diodes. Sso they will only run for seconds. With 250 mA, the heat sink did not even get warm.
I could, of course, build a perfect heat sink, but this device works well for his task.
But I have another question. I could not find how to send a personal message to a member. Any advice is welcome.
You can click on the envelope icon next to your user name at the top of the page to start a private conversation. If the heat sink doesn't warm up this could be a sign that it doesn't transfer heat well from the diode. For only a couple of seconds at 250 mA, the diode could be just getting a few degrees hotter than ambient. It depends on the diode used.
