A transistor, stands for transfer of resistance, is commonly used to amplify current. Choosing Battery for Robots.

Choosing Motor For Robots. BC is mainly used for amplification and switching purposes. Skip to main content.

To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. It has a maximum current gain of BC has a gain value of tothis value determines the amplification capacity of the transistor.

TL — Programmable Reference Voltage. The value of I B should not exceed mA. Of the above types common emitter type is the popular and mostly used configuration.

Amplifier modules like Audio amplifiers, signal Amplifier etc.

SPI Module of Arduino. The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. Submitted by admin on 30 August The input signal at base is amplified and taken at the emitter. Interface GPS with Arduino. 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.


Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. Virgin Galactic — Commercial Space Flight. The value of this resistor R B can be calculated using below formulae.

Interface SD Card with Arduino. In the absence of base signal, it gets completely off. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. Arduino based GPS receiver.

When this transistor is fully biased then it can allow a maximum of mA to flow datasheer the collector and emitter. BC is a NPN transistor hence the collector and emitter will be left open Reverse biased when the base pin is held at ground and dataasheet be closed Forward biased when a signal is provided to base pin. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base.

Transistor BC547

Its equivalent transistors are BC and BC BC is used in common emitter configuration for amplifiers. If you are designing a PCD or Perf board with this component then the following picture from the Datasheet will be useful to know its package type and dimensions. When dayasheet transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.


This high-density System-in-Package SiP integrates controller, power switches, and support components. As mentioned the biasing current should maximum of 5mA. 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.

The transistor terminals require a fixed DC voltage to operate in the desired datasheft of its characteristic curves.

Complete Technical Details can be found at the datasheet give at the end d547 this page. It can amplify power, voltage and current at different configurations.

BC is an NPN bi-polar junction transistor. This is known as the biasing.

For amplification applications, the transistor is biased such that it is partly on for all input conditions. The voltage datasgeet is the commonly used biasing mode.
