It was originally made in the TO-18 metal can as shown in the picture. Thus, the transistor controls the power flow to another part of the circuit. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds. The transistor is a 3 terminal & 2 junction semiconductor device which is used for switching or amplifying purposes. BC549C is an NPN transistor in a small plastic case. These are not direct substitutes for 2N2222. ![]() BC558 is a PNP transistor thats the opposite kind, in which current flows in the other direction.
