Hello, I am currently building my first flight computer, I know MOSFETs are best for igniting the ejection charge, I don’t have a MOSFET but I do have a PN2222 transistor, will this work? I will be running 600ma at 9 volts through it which is within the max rating of the transistor. Should I just go buy a MOSFET? If so, are there any models you would recommend? The power source for the ignition is separate than the power source for the flight computer. Thank you.
