The value of this resistor R B can be calculated using below formulae. 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 mentioned the biasing current should maximum of 5mA.

A Transistors acts as an Amplifier when operating in Active Region. The value of I B should not exceed mA.

When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. The value of this resistor R B can be calculated using 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.

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.

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.

TL — Programmable Reference Voltage. Complete Technical Details can be found at the BC datasheet given at the end of this page.

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 this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. 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 trznsistor required amount of current to the base pin. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae.

Datashret bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. Dtaasheet 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 has a gain value of tothis value determines the amplification capacity of the transistor.

Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. Amplifier modules like Audio amplifiers, signal Amplifier etc.

It can amplify power, voltage and current at different configurations. It can amplify power, voltage and current at different configurations. Submitted by admin on 30 August BC has a gain value of tothis value determines the amplification capacity of the transistor. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.

Amplifier modules like Audio amplifiers, signal Amplifier etc. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with 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 dataseet supplying the required amount of current to the base pin. Of the above types common emitter type is the popular and mostly used configuration.

When a transistor is datqsheet as a switch it is operated in the Saturation and Cut-Off Region as explained above. 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. A Transistors acts as an Amplifier when operating in Active Region. As mentioned the biasing current should maximum of 5mA. Of the above types common emitter type is the popular and mostly used configuration.
