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.

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.

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. It can amplify power, voltage and current at different configurations.

To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. As mentioned the biasing current should maximum of 5mA. If you are designing a PCD or Perf board with this component then the following picture from the Datasheet will be useful to know its package type and dimensions. The value of this resistor R B can be calculated using below formulae. TL — Programmable Reference Voltage.

As discussed a transistor will act as an Open switch during Forward Transietor and as a Closed switch during Reverse Bias, this biasing can be achieved by supplying the required amount of current to the base pin.

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.

Current flows in through collector. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Amplifier modules like Audio amplifiers, signal Amplifier etc. TL — Programmable Reference Voltage. 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. 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.

Anything more than 5mA will transistoe 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 the Base Emitter voltage could be around mV.

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. Of the above types common emitter type hransistor the popular and mostly used configuration. The value of I B should not exceed mA.

BC is a NPN transistor hence the collector and emitter will be left open Reverse biased when the base pin is held at ground and will be closed Forward biased when a signal is provided to base pin. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. BC has a gain value of tothis value determines the amplification capacity of the transistor.

It can amplify power, voltage and current at different configurations. BC has a gain value of tothis value determines the amplification capacity of the 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. Current Drains out through emitter. The value of I B should not exceed mA.

Some 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 trsnsistor Amplifier the DC current gain of the Transistor can be calculated by using the below formulae.

As mentioned the biasing current should maximum of 5mA. Submitted by admin on 26 October To bias a transistor we have to supply current to base pin, this current I B should be limited to transishor. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae.
