I just bought a pack of 2222A NPN transistors from a local electronics shop.
I found some datasheets online (e.g. https://www.onsemi.com/pdf/datasheet/p2n2222a-d.pdf ) that say the emitter-base voltage is 6v.
Does that mean that I cannot use this transistor with a 3v or 5v power supply?
(In the past I never looked at the specs and just wired the transistor with a resistor at the base, and it all worked. I am trying to reconcile my cowboy experience with a new practice of reading datasheets, and I am getting confused.)
