I have a 2N2222A transistor that I use in a circuit coupled with an opamp. Its function is to act as a current booster.
The collector is always supplied with 12V and the emitter can be set anywhere between 0 - 8 V. I was not aware about overheating my transistor, and I believe I've burnt my transistor when I have a current of about 200mA passing through it, when the VC was 12V and VE about 6V.
I want to replace it with one that can handle the power yet not hinder performance. I am also willing to buy heat sinks for the packages.
The range of current I am expecting for this transistor to drive is anywhere between 0 and 300 mA.
