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. The value of I B should not exceed mA. TL — Programmable Reference Voltage. Amplifier modules like Audio amplifiers, signal Amplifier etc.

Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. Current Drains out through emitter. When base current is removed the transistor becomes fully datasheett, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV.

BC is a PNP transistor hence the collector and emitter will be closed Forward biased when the dafasheet pin is held at ground and will be opened Reverse biased when a signal is provided to base pin.

Complete Technical Details can be found at the BC datasheet given at the end of this page. Current flows in through collector. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Of the above types common emitter type is the popular and mostly used configuration.

BC Transistor Pinout, Description, Equivalent & Datasheet

To bias a transistor we have to supply current to base pin, bcc557a current I B should be limited to 5mA. BC has a gain value of tothis value determines the amplification capacity of the transistor.

As mentioned the biasing current should maximum of 5mA. Submitted by admin on 26 October It can amplify power, voltage and current at different configurations.

As discussed a transistor will act as an Open switch during Forward Bias and as a Closed switch during Datasheett Bias, this biasing can be achieved by supplying the required amount of current to the base pin. The value of this resistor R B can be calculated using below formulae.

A Transistors acts as an Amplifier when operating in Active Region. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae.

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

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.

Controls the biasing of 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.
