Some b157 the configurations used in amplifier circuits are Common emitter amplifier Common collector amplifier Common base amplifier Of the above types common emitter type is the popular and mostly used configuration.
BC157 Datasheet, Equivalent, Cross Reference Search
Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and b1c57 Base Emitter voltage could be around mV.
To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. Complete Technical Details can be found at the BC datasheet given at the end of this page.
The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. The value of I B should dstasheet exceed mA. Amplifier modules like Audio amplifiers, signal Amplifier etc.
BC Transistor Pinout, Description, Equivalent & Datasheet
It can amplify power, voltage and current at different configurations. BC Transistor as switch When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.
As discussed a transistor will act as an Open bc15 during Forward Bias and as a Closed switch during Reverse Bias, this biasing can be achieved by supplying the required amount of current to the base pin. BC has a gain value of tothis value determines the amplification capacity of the transistor. Current Drains out through emitter.
If you are designing a PCD or Perf board with this component then the following picture from the BC Datasheet will be useful to know its package type and dimensions.
When a transistor is used as a switch it is operated in datashest Saturation and Cut-Off Region as explained above.
BC is a PNP transistor hence the collector and emitter will be closed Forward biased when the datasheeg pin is held at ground and will be opened Reverse biased when a signal is provided to base pin. Controls the biasing of transistor.

Current flows in through collector. The value of this resistor R B can be calculated using below formulae.
When this transistor is fully biased cb157 it can allow a maximum of mA to flow across the collector and emitter. As mentioned the biasing current should maximum of 5mA. TL — Programmable Reference Voltage.

When uses as an Amplifier the Datashet current gain of the Transistor can be calculated by using the below formulae. Of the above types common emitter type is the popular and mostly used configuration.
