CB Datasheet, PDF – Alldatasheet

The value of I B should not exceed mA. The value of this resistor Hransistor B can be calculated using below formulae. It can amplify power, voltage and current at different configurations.

The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume c57b than mA using this transistor. 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.


As discussed a transistor will act as an Open switch during Forward Bias and as a Closed switch during Reverse Bias, trasistor biasing can be achieved by supplying the required amount of current to the base pin. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.

Current Drains out through emitter. 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. 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 calculated by using the below formulae. If you are designing a PCD or Perf board with this component then the following picture c575b the BC Datasheet will be useful to know its package type and dimensions.

Amplifier modules like Audio amplifiers, signal Amplifier etc. Controls the biasing of transistor. As mentioned the biasing current should maximum of 5mA.


TL — Programmable Reference Voltage. A Transistors acts as an Amplifier when operating in Active Region. Complete Technical Details can be found at the BC datasheet given at the end of this page.

c557b 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 transistod popular and mostly used configuration. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. Current flows in through collector. 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.

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