BC is a general purpose PNP transistor.

BC Pinout, Configuration, Circuit As Switch & Amplifier

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.

Virgin Galactic — Commercial Space Flight. 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.

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

In the absence of base signal, it gets completely off. SPI Module of Arduino. 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.


BC has a gain value of to ; this value determines the amplification capacity of the transistor. As discussed a transistor will act 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.

What is Web Browser. Choosing Motor For Robots. The value of this resistor RB can be calculated using below formulae.

Transistor BC558

Choosing Battery for Robots. It can amplify power, voltage and current at different configurations. This high-density System-in-Package SiP integrates controller, power switches, and support components. The voltage divider is the commonly used biasing mode. Interface GPS with Arduino. The DC current gain varies in range transistoe Skip to main content.

Amplifier modules like Audio amplifiers, signal Amplifier etc. BC is used in common emitter configuration for amplifiers. Submitted by admin on 26 March When this transistor is fully biased then it can allow continues current of mA to flow across the collector and emitter.

For switching applications, transistor is biased so that it remains fully on if there is a signal at its base. Of the above types common emitter type which amplifies voltage is the popular and mostly used configuration. A Transistors acts as an Amplifier when operating in Active Region. TL — Programmable Reference Voltage. It is used in transidtor and amplifier applications.


Tranwistor BC because of this large gain value is normally used to as a audio amplifier. A resistor is always trransistor in series with base pin to limit the base current. The input signal at base is amplified and taken at the emitter. It is also used as a complement for transistors BC to BC In the below GIF you can notice the transistor being switched for a low voltage 1v audio signal.

Complete Technical Details can be found in the BC datasheet given at the end of this page.

For amplification applications, the transistor is biased such that it is partly on for all input conditions. Interface SD Card with Arduino. This is known as the biasing. Arduino based GPS receiver.

When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves. Where an input signal of low voltage is amplified switched to high voltages t0 drive loads like speakers.
