Simulating BJT 2N2222 in LTspice. 5 mA collector current when B and E shorted

I am simulating NPN 2N2222 in LTspice. When I short base and emitter, the collector has peak up to 6 mA. Should not it be in terms of nA when there is 0 V between base and emitter? Can you please ...

How do I saturate an NPN transistor for switching?

I want to use a 12F675 to turn on two LEDs. After a little research, I decided to use a 2N2222A NPN transistor and 2 LEDs in series (2V-drop 20mA consumption.) As I read in datasheet, microcontroller ...

Creating a 3.3 V audio amplifier using an NPN 2N2222 transistor

It has been way too long since I did anything with transistor amplifiers. I am trying to find an example of a 3.3 V NPN transistor amplifier preferably based around a 2N2222 transistor. I have lost ...
