A Transistors acts as an Amplifier when operating in Active Region. It can amplify power, voltage and current at different configurations. B157 of 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.

When uses as an Amplifier the DC current gain of the Transistor can be bv157 by using the below formulae. 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.


TL — Programmable Reference Voltage. Complete Technical Details can be found at the BC datasheet given at the end of this datasheett. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Current flows in through collector.

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. BC has a gain value of tothis value determines the amplification capacity of the transistor.

BC Transistor Pinout, Description, Equivalent & Datasheet

When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. Anything dztasheet than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.

Current Drains out through emitter. BC Transistor as switch When a transistor is used as a switch it is operated in satasheet Saturation and Cut-Off Region as explained above.

Of the above types common emitter type is the popular and mostly used configuration. Submitted by admin on 26 October The value of I B datashheet not exceed mA.


BC is a PNP transistor hence the collector and emitter will be closed Forward biased when the base pin is held at ground and will be opened Reverse biased when a signal is provided to base pin. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.

As mentioned the biasing current should maximum of 5mA. Amplifier modules like Audio amplifiers, signal Amplifier etc. As discussed a transistor will act as an Open switch 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. The value of this resistor R B can be calculated using below formulae. Controls the biasing of transistor.
