It can amplify power, voltage and current at different configurations. BC as switch When a transistor is used as a switch it is operated in the Saturation and Cut-Off Dwtasheet as explained above.

BC Datasheet, Equivalent, Cross Reference Search. Transistor Catalog

Of the above types common emitter type which amplifies voltage is the popular and mostly used configuration. When base current is removed the transistor becomes fully off, this stage is called as hc558 Cut-off Region and the Base Emitter voltage could be around mV.

Interface SD Card with Arduino.

The value of this resistor RB can be calculated using below formulae. BC has a gain value of to ; this value determines the amplification capacity of the transistor. In the below GIF you can notice the transistor being switched for a low voltage 1v audio signal. Choosing Battery for Robots.

This high-density System-in-Package SiP integrates controller, power switches, and support components. TL — Programmable Reference Voltage. It is also used as a complement for transistors BC to BC Submitted by admin on 26 March Virgin Galactic — Commercial Space Flight. In the absence of base signal, it gets completely off. SPI Module of Arduino. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae.


It is used in switching and amplifier applications. BC is used in common emitter configuration for amplifiers.

BC transistog 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. Choosing Motor For Robots. Amplifier modules like Audio amplifiers, signal Amplifier etc.

The input signal at base is amplified and taken at the emitter. 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. The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves. The voltage divider is the commonly used biasing mode. Interface GPS with Arduino.

Arduino based GPS receiver. BC is a general purpose PNP transistor. 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. 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.


This is known as the biasing. Complete Technical Details can be found in the BC datasheet given at the end of this page. Where an input signal of low voltage is amplified switched to high voltages t0 drive loads like speakers. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.

A Transistors acts as an Amplifier when operating in Active Region. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base.

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.

The BC because of this large gain value is normally used to as a audio amplifier.
