Some of the configurations used in amplifier circuits transistkr Common emitter amplifier Common collector amplifier Common base amplifier Of the above types common emitter type is the popular and mostly used configuration. 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.

A Transistors acts as an Amplifier when operating in Active Region. Anything more than 5mA will kill the Transistor; hence transkstor resistor is always added in series with 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 TL — Programmable Reference Voltage. 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 this resistor R B can be calculated using below formulae. BC is a PNP transistor hence the collector and emitter will be closed Forward biased when transistkr base pin is held at ground and will be opened Reverse biased when a signal is provided to base pin.

It can amplify power, voltage and current at different configurations. Controls the biasing of transistor. If you are designing a PCD or Perf board with this component then the following picture from the Trsnsistor Datasheet will be useful to know its package type and dimensions. Of the above types common emitter type is the popular and mostly used configuration.

As mentioned the biasing current should maximum of 5mA. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

Complete Technical Details can be found at the BC datasheet given at the end of this page. 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 transiator of current to the base pin. When a transistor transstor used as a switch it is operated in the Saturation and Cut-Off Region as explained above.

Amplifier modules like Audio amplifiers, signal Amplifier etc. BC has a gain value of tothis value determines the amplification capacity of the transistor.

Current flows in through collector. 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 c557v limited to 5mA.

Current Drains out through 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.
