Arduino based GPS receiver. It is used in switching and amplifier applications. Virgin Galactic — Commercial Space Flight.

When this transistor is fully biased then it can allow continues current of mA to flow across the collector and emitter. BC is used in common emitter configuration for amplifiers.

When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. 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. It is also used as a complement for transistors BC to BC In the absence of base signal, it gets completely off. Amplifier modules like Audio amplifiers, signal Amplifier etc.

It can amplify power, voltage and current at different configurations.


Choosing Battery for Robots. The DC current gain varies in range to The voltage divider is the commonly used biasing mode. SPI Module of Arduino. 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. In the below GIF you can notice the transistor being switched for a low datashwet 1v audio signal. 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.

The input signal at base is amplified and taken at the emitter. The value of this resistor RB can be calculated using below formulae.

BC Transistor | BC Datasheet

A Transistors acts as an Amplifier when operating in Active Region. A resistor is always added in series with base pin to limit the base current. This is known as the biasing. For amplification applications, the transistor is biased such that it is partly on for all input conditions. 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.

BC558 Datasheet, Equivalent, Cross Reference Search

The BC because of this large gain value is normally used to as a audio amplifier. BC has a gain value of to ; this value determines the amplification capacity of the transistor.


This high-density System-in-Package SiP integrates controller, power switches, and support components. What is Web Browser. Submitted by admin on 26 March BC is a general purpose PNP transistor.

Where an input signal of low voltage is amplified switched to high voltages t0 drive loads like speakers. Complete Technical Details can be found in the BC datasheet given at the end of this page. The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves.

Transistor BC558

TL — Programmable Reference Voltage. 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. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base. Skip to main content. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.
