BC Transistor Pinout, Description, Equivalent & Datasheet

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. Ttansistor — Programmable Reference Voltage.

Submitted by admin on 26 October Complete Technical Details can be found at the BC datasheet given at the end of this page. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

BC has a gain value of tothis value determines the amplification capacity of the transistor. A Transistors acts as an Amplifier when operating in Active Region. Anything more than 5mA will kill the Transistor; tgansistor a resistor is always added transisfor series with base pin. 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.

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

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. BC is transixtor 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 tranisstor this resistor R B can be calculated using below formulae. 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. The value of I Traansistor should not exceed mA.

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

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