I must have used a million of these in prototypes. Very hard to blow up. Even if you're switching over 1A! Only the metal cased versions, mind you. The plastic packages pop like balloons!

@LStacey Thanks for mentioning that out ... (Y)

This used to be my universal NPN transistor for many circuits. Some packages allowed 1A switching which was great for such a small part. Have used this with the good old 2N2907 as a complimentary output pair for a small amplifier on many an occasion in the past.

2N2222, a new electronic component - not true! I've been using them since the eighties.
As to the discussion, where is it?
Any fool can regurgitate the bullet-points of a datasheet. THE two key items of initial interest are absent i.e. gain and bandwidth. These along with power rating, max. Ic and max. Vce are needed for the selection process.

@meandray I meant I am gonna share a new tutorial on electronic components, i kind of use such starting lines sorry for the confussion. I have also added a link which will give you a more detailed description of this IC. Please check that one out as well. Here its a basic introduction to let people know what is 2n2222. Have a good day. :)
