The value of this resistor R B can be calculated using below formulae.

Anything more than 5mA will kill the Transistoor hence a resistor is always added in series with base pin. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. A Transistors acts as an Amplifier when operating in Active Region.

BC has a gain value of tothis value determines the amplification capacity of the transistor. C5577b the above types common emitter type is the popular and mostly used configuration. Current Drains out through emitter.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. 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.


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

Submitted by admin on 26 October If you are designing a PCD or Perf board with transiator component then the following picture from the BC Datasheet will be useful to know its package type and dimensions.

Amplifier modules like Audio amplifiers, signal Amplifier transisror. Controls the biasing of transistor. 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 Transistor as switch When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. BC is a PNP transistor hence the collector and emitter will be tarnsistor Forward biased when the base pin is held at ground and will be opened Reverse biased when a signal is provided to base pin. Complete Technical Details can be found at the BC datasheet given at the end of this page.


Current flows in through collector. Some of the configurations used in amplifier circuits are Common emitter amplifier Common collector amplifier Common base amplifier Of the above types common emitter trznsistor is the popular and mostly used configuration. TL — Programmable Reference Voltage.

As mentioned the biasing current should maximum of 5mA. The value of I B should not exceed mA. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. It can amplify power, voltage and current at different configurations.
