A resistor is always added in series with base pin to limit the base current. When this transistor is fully biased then it can allow continues current of mA to flow across the collector and emitter.

The voltage divider is the commonly used biasing mode. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base. This high-density System-in-Package SiP integrates controller, power switches, and support components. BC is used in common emitter configuration for amplifiers.

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

The value of this resistor RB can be calculated using below formulae. It is used in switching and amplifier applications. What is Web Browser.


Also note bc5558 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. Amplifier modules like Audio amplifiers, signal Amplifier etc. The input signal at base is amplified and taken at the emitter. Complete Technical Details can be found in the BC dataheet given at the end of this page.

BC has a gain value of to ; this value determines the amplification capacity of the transistor. Submitted by admin on 26 March Choosing Motor For Robots.

The BC because of this large gain value is normally used to as a audio amplifier. Interface SD Card with Arduino.

In the below GIF you can notice the transistor being switched for a low voltage 1v audio signal. SPI Module of Arduino. 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 transisttor by supplying the required amount of current to the base pin.

BC Pinout, Configuration, Circuit As Switch & Amplifier

Transistoor is a general purpose PNP transistor. Skip to main content. Virgin Galactic — Commercial Space Flight. The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves.


This is known as the biasing. Interface GPS with Arduino. It can amplify power, voltage and current at different configurations. For amplification applications, the transistor is biased such that it is partly on for all input conditions.

When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae.

Of the above types common emitter type which amplifies voltage is the popular and mostly used configuration. BC as switch When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as datashee above.

BC558 Datasheet, Equivalent, Cross Reference Search

A Transistors acts as an Amplifier when operating in Active Region. 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.

Arduino based GPS receiver.

Choosing Battery for Robots. The DC current gain varies in range to In the absence of base signal, it gets completely off.

It is also used as a complement for transistors BC to BC
