The symbol of the BC546 transistor is also represented in the above figure. It is important to notice here that while pointing out the leads of the transistor the flat face of the transistor should be facing. This applies for all transistors.


BC546 NPN transistor Basic Description:


BC546 is a general purpose transistor and mainly employed for switching and AF (audio frequency) amplifier applications. The BC546 transistor gets on when the Base-Emitter Voltage exceeds 0.55 volts. The Transfer characteristics of the transistor is defined as the relation between the input and output voltage.

BC 546 Transistor Type:
