When base current is dstasheet the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. A resistor is always added in series with base pin to limit the base current. In the below GIF you can notice the transistor being switched for a low voltage 1v audio signal.

For amplification applications, the transistor is biased such that it is partly on for all input conditions. Interface GPS with Arduino. It can amplify power, voltage and current at different configurations. Choosing Battery for Robots. BC has a gain value of to ; this value determines the amplification capacity of the transistor.

BC is a general purpose PNP transistor. Also note that a PNP transistor is always used for high side switching, meaning the collector is connected to power and emitter to catasheet that is to be switched. It is also used as a complement for transistors BC to BC What is Web Browser.


Where an input signal of low voltage is amplified switched to high voltages t0 drive loads like speakers. Arduino based GPS receiver. Complete Technical Details can be found in the BC datasheet given at the end of this page.

Of the above types common emitter type which amplifies voltage is the popular and mostly used configuration. When this transistor is fully biased then it can allow continues current of mA to flow across the collector and emitter. BC as switch When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.

Virgin Galactic — Commercial Space Flight.

Transistor BC558

Amplifier modules like Audio amplifiers, signal Amplifier etc. Interface SD Card with Arduino. The input signal at base is amplified and taken at the emitter. This high-density System-in-Package SiP integrates controller, power switches, and support components.

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

BC Pinout, Configuration, Circuit As Switch & Amplifier

Submitted by admin on 26 March In the absence of base signal, it gets completely off. The DC current gain varies in range to The BC because of this large gain value is normally used to as a audio amplifier.


SPI Module of Arduino. BC is used in common emitter configuration for amplifiers. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base.

Skip to main content.

A Transistors acts as an Amplifier when operating in Active Region. As discussed a transistor will dafasheet 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.

The value of this resistor RB can be calculated using below formulae. The voltage divider is the commonly cb558 biasing mode. Choosing Motor For Robots. This is known as the biasing. BC is a PNP transistor hence the collector and emitter will be closed Forward biased when the base pin is held at gc558 and will be opened Reverse biased when a signal is provided to base pin.

It is used in switching and amplifier applications. The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves.
