Interface SD Card with Arduino. What is Web Browser. TL — Programmable Reference Voltage.

Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. Choosing Battery for Robots. Amplifier modules like Audio amplifiers, signal Amplifier etc.

BC is mainly used for amplification and switching purposes. BC is used in common emitter configuration for amplifiers. The input signal at base is amplified and taken at the emitter. A transistor, stands for transfer of resistance, is commonly used to amplify current. The maximum amount of current that could datashret 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 Datashert equivalent transistors are BC and BC To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.


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

BC Transistor: Pinout, Diagrams, Equivalents & Datasheet

When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage datashedt be around mV. In the absence of base signal, datasehet gets completely off. BC has a gain value of tothis value determines the amplification capacity of the transistor. Interface GPS with Arduino. The value of this resistor R B can be calculated using below formulae. This is known as the biasing. A Transistors acts as an Amplifier when operating in Active Region.

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. Skip to main content.

C547 Datasheet

When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. It has a maximum current gain of When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. When a transistor is used as dtasheet switch it is operated in the Saturation and Cut-Off Datasheett as explained above. As mentioned the biasing current should maximum of 5mA. Arduino based GPS receiver. Complete Technical Details can be found at the datasheet give at the end of this page.


This high-density System-in-Package SiP integrates controller, power switches, and support components. BC is an NPN bi-polar junction transistor. Virgin Galactic — Commercial Space Datazheet. The value of I B should not exceed mA. Of the above types common emitter type is the popular and mostly used configuration.

BC Datasheet, Equivalent, Cross Reference Search. Transistor Catalog

For amplification applications, the transistor is biased such that it is partly on for all input conditions. BC is a NPN f547 hence the collector and emitter will be left open Reverse biased when the base pin is held at ground and will be closed Forward biased when a signal is provided to base pin.

SPI Module of Arduino. Choosing Motor For Robots. The voltage divider is the commonly used biasing mode.

Transistor BC547

It can amplify power, voltage and current at different configurations. If you are designing a PCD or Perf board with this component then the following picture dztasheet the Datasheet will be useful to know its package type and dimensions. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base.
