The BC556 is a PNP Transistor, hence we need to provide zero volts to the base of the transistor to turn it on. This transistor comes with many different versions, if you are using this transistor as an amplifier make sure you check the gain of the transistor from the datasheet that can be found down below, because of different versions the gain value differs which can completely ruin your calculations. The maximum collector current of this transistor is rated at -100mA with a peak current of -200mA, this transistor has an emitter-base voltage of -5V. This transistor has a collector-emitter voltage of -65V and a collector base voltage of -80V. This transistor can operate with 150*C.
When this transistor is in biased condition, then it can allow a maximum current of 100mA across CE(Collector-Emitter) Junction, this state of the transistor is called the saturation state,�and driving a load that consumes more current than 100mA may damage the device in this condition. As you already may know a transistor is a current-controlled device�so when the base current is removed the transistor becomes fully off, in this stage the transistor is working in its Cut-off Region and the Base Emitter voltage could be around 660 mV.
BC556 Transistor�has a gain of 125 to 450 which determines the amplification capacity of the transistor, the peak current that can be flown through this transistor is 200maA, which combines with the gain value makes this transistor a perfect choice for a preamplifier for audio amplifier.

A PNP transistor is made up of a doped N-Type material that is sanduzied in between two P-Type materials. In a PNP transistor holes are the majority charge carrier that means the holes are emitted by the collector and collected by the emitter, the main difference between the NPN and PNP transistor is the flow of electrons runs from collector to emitter but in a PNP transistor the electrons run from emitter to collector, as a result, a PNP transistor turns on when there is a low or 0V on the base of the transistor. Where an NPN transistor is on when a positive or high signal is applied.
