Hi folks. I am new to the group and I am very happy to have found it. Someone might be able to help me and make a reccomendadtion on what type of device I should use for the following:
I am trying to find a transistor to use as a switch to handle some pretty hefty current and cant seem to find one. I need to find a way to switch +200VDC at around 3 Amperes, (possibly 5 Amperes surge). I can only drive it with a + 5V TTL 24 mA source or 64 mA ground sink max. I havent had any luck finding a PNP transistor that will let me do that. Is there something better then a transistor to use? I don't really want to use a relay because of the reliability of the mechanical contacts at that voltage, and it would be cost prohibitive since I need to build many of these for my project. This is a personal project and is not for profit. If you have any suggestions, I would really appreciate the help. Thanks so much!
