TL — Programmable Reference Voltage. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.

Current flows in through collector. Current Drains out through emitter.

The value of I B should not exceed mA. Transisfor 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. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin.

When a transisor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. A Transistors acts as an Amplifier tansistor 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. When uses as an Amplifier the DC current gain of the Transistor can be c557h by using the below formulae. 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.

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

BC Transistor Pinout, Description, Equivalent & Datasheet

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

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. Submitted by admin on 26 October 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.

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. It can amplify power, voltage and current at different configurations. 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. BC has a gain value of tothis value determines the amplification capacity of the transistor.

Controls the biasing of transistor. Complete Technical Details can be found at the BC datasheet ttransistor at the end of this page.

The maximum amount of current that could flow through trandistor Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor.
