The pinout of the BC558 Transistor is as shown in the following figure:
The symbol of the BC558 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.
BC558 Basic Description:
BC558 is a general purpose transistor and mainly employed for switching and AF (audio frequency) amplifier applications. The BC558 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 558 Transistor Type:
- Bi-Polar NPN
BC558 Absolute Maximum Rating at Room Temperature:
