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.

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

When base transistoe 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.

c557b transistor

The value of this resistor R B can be calculated using below formulae. Amplifier modules like Audio amplifiers, signal Amplifier etc.

Current flows in through collector. 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. The value of I B should not exceed mA.

Controls the biasing of transistor. TL — Programmable Reference Voltage.

Complete Technical Details can be found at the BC c5557b given at the end of this page. 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. BC is a PNP transistor hence the collector and emitter will be closed Forward biased when transistod base pin is held at ground and will be opened Reverse biased when a signal is provided to base pin.

Of the above types common emitter type is the popular and mostly used configuration. Some of the configurations used in amplifier circuits are Tramsistor emitter amplifier Common collector amplifier Common base amplifier Of the above types common emitter type is the popular and mostly used configuration.

Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. When uses as an Trannsistor the DC current gain of the Transistor can be calculated by using the below formulae. 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 It can amplify power, voltage and current at different configurations. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. Current Drains out through emitter.

BC has a gain fransistor of tothis value determines the amplification capacity of the transistor. As mentioned the biasing current should maximum of 5mA. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. A Transistors acts as an Amplifier when operating in Active Region.
