TL — Programmable Reference Voltage.

This is known as the biasing. Arduino based GPS receiver. Virgin Galactic — Commercial Space Flight.

Transistor BC558

Skip to main content. 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.

When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base.

BC has a gain value of to ; this value determines the amplification capacity of the transistor. 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. Interface SD Card with Arduino. Submitted by admin on 26 March 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 vc558 pin.


It is used in switching and amplifier applications. BC as switch When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. 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. It can amplify power, voltage and current at different configurations. 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. What is Web Browser. The value of this resistor RB can be calculated using below formulae.

For amplification applications, the transistor is biased such that it is partly on for all input conditions. As discussed a transistor will act as an Open switch during Forward Bias and as a closed switch during Reverse Dataasheet, this biasing can be achieved by supplying the required amount of current to the base pin.


In the absence daatsheet base signal, it gets completely off. Interface GPS with Arduino. Complete Technical Details can be found in the BC datasheet given at the end of this page. The DC current gain varies in range to BC is used in common emitter configuration for amplifiers. 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. BC is a general purpose PNP transistor. The BC because of this large gain value is normally used to as a datashewt amplifier. The voltage divider bc558 the commonly used biasing mode. It is also used as a complement for transistors BC to BC
