Description: This is the P2N2222A, an NPN silicon BJT (Bipolar Junction Transistor). This little transistor can help in your project by being used to help drive large loads or amplifying or switching applications. The P2N2222A is specifically rated at 40V and 600mA max.
This is the transistor used in our Sparkfun Inventor’s Kits.
Based on 1 ratings:
It is totally doped! The P is even better then the N as far as doping goes.
