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 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.

Complete Technical Details can be found at the BC datasheet given at the end of this page.

BC has a gain value of tothis value determines the amplification capacity c5557b the transistor. As mentioned the biasing current should maximum of 5mA.

Controls the biasing of transistor. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.

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 Drains out through emitter.

Current flows in through collector. 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. A Transistors acts as an Amplifier when operating in Active Region. The value of this resistor R B can be calculated using below formulae.

To bias a transistor we have to supply current to base pin, this current I B trahsistor be limited to 5mA.

The value of I B should not exceed mA. TL — Programmable Reference Voltage.

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

It can amplify power, voltage and current at different configurations. Amplifier modules like Audio amplifiers, signal Amplifier etc.

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. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Submitted by admin on 26 October Of the above types common emitter type is the popular and mostly used configuration.
