I am working on a project with Nixie tubes which require a high voltage supply. I have some "indicator dot" tubes that require 90V DC, and I want to turn them on/off using a microcontroller control line.
I am thinking a transistor is the right tool for this, but I am not familiar enough with the different types to know what will work (BJT vs MOSFET, NPN vs PNP, high-side vs low-side switching).
Please forgive this schematic. It is probably wrong; it is merely indicative of what I want to accomplish.. that is the question I am asking. What is the right way to do this, and what type of transistor should I use? Specific part numbers would also be appreciated.
To be clear, I don't need to amplify any voltages, I already have the voltage supply I need for the 90V line.
