The value of I B should not exceed mA. Complete Technical Details can be found at the BC datasheet given at the end of this page. As mentioned the biasing current should maximum of 5mA.

As discussed a transistor will act as an Open datasheeet 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.

Submitted by admin on 26 October The value of this resistor R B can be calculated using below formulae.

When this transistor is datahseet biased then it can allow a maximum of mA to flow across the collector and emitter. A Transistors acts as an Amplifier when operating in Active Region.

Anything more than 5mA will kill the Transistor; 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.

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

Of the above types common emitter type is the popular and mostly used configuration. Controls the biasing of transistor. Current flows in through collector. When base current is removed the datashee 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 datasheet be useful to know its package type and dimensions. 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.

Amplifier modules like Audio amplifiers, signal Amplifier etc. 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.

It can amplify power, voltage and current at different configurations. Current Drains out through emitter.

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