When this transistor is fully biased then it can allow continues current of mA to flow across the collector and emitter.

BC Transistor | BC Datasheet

This is known as the biasing. In the below GIF you can notice the transistor being switched for a low voltage 1v audio signal. It is also used as a complement for transistors BC to BC BC has a gain value of to ; this value determines the amplification capacity of the transistor.

The input signal at base is amplified and taken at the emitter. 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.


Where an input signal of low voltage is amplified switched to high voltages t0 drive loads like speakers. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base. Amplifier modules like Audio amplifiers, signal Amplifier etc.

Also note that a PNP transistor is always used for high side switching, meaning the collector is connected to power and emitter to load that is to be switched. Datashedt SD Card with Arduino. The voltage divider is the commonly used biasing mode.

Arduino based GPS receiver. The value of this resistor RB can be calculated using below formulae. A Transistors acts datasheett an Amplifier when operating in Active Region. Choosing Motor For Robots. What is Web Browser. Skip to main content. It can amplify power, voltage and current at different configurations.

It is used in switching and amplifier applications. Virgin Galactic — Commercial Space Flight. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. SPI Module of Arduino. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. BC is a general purpose PNP transistor. Submitted by admin on 26 March TL — Programmable Reference Voltage.

Of the above types common emitter type which amplifies voltage is the popular and mostly used configuration. In the absence of base signal, it gets completely off.

Transistor BC558

Complete Technical Details can be found in the BC datasheet given at the end of this page. This high-density System-in-Package SiP integrates controller, power switches, and support components. The transistor terminals require a fixed DC voltage to operate in the desired region of datasueet characteristic curves.


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

Choosing Battery for Robots. BC is used in common emitter configuration for amplifiers. BC as datadheet When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. Interface GPS with Arduino.

bc5558 The DC current gain varies in range to For amplification applications, the transistor is biased such that it is partly on for all input conditions. A resistor is always added in series with base pin to limit the base current. The BC because of this large gain value is normally used to as a audio amplifier.
