BC547 Datasheet, Equivalent, Cross Reference Search

Of the above types common emitter type is the popular and mostly used configuration. 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 will be closed Darasheet biased when a signal is provided to base pin.

As mentioned the biasing current should maximum of 5mA. BC is mainly used for amplification datasbeet switching purposes. This is known as the biasing.

Interface SD Card with Arduino. In the absence of base signal, it gets completely off. To bias a transistor we have to supply current to base pin, this current Datashedt B should be limited to 5mA. It has a maximum current gain of When base current is removed the transistor becomes fully off, this stage is called dqtasheet the Cut-off Region and the Base Emitter voltage could be around mV. What is Web Browser. BC has a gain value of tothis value determines the amplification capacity of the transistor.


This high-density System-in-Package SiP integrates controller, power switches, and support components. The input signal at base is amplified and taken at the emitter. SPI Module of Arduino.

For amplification applications, the transistor is biased such that it is partly on for all input conditions. TL — Programmable Reference Voltage. If you are designing a PCD or Perf board with this component then the following picture from the Datasheet will be useful datawheet know its package type and dimensions. Choosing Battery for Robots.

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. Virgin Galactic — Commercial Space Flight. Submitted by admin on 30 August Its equivalent transistors are BC and BC Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin.

The value of this resistor R B can be calculated using below formulae. When uses as an Amplifier adtasheet DC current gain of the Transistor can be calculated by using the below formulae. BC is used in common emitter configuration for amplifiers. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.


The value of I B should datashret exceed mA. The maximum amount of current that could flow through the Collector pin is datashee, hence we cannot connect loads that consume more than mA using this transistor.

A transistor, stands for transfer of resistance, is commonly used to amplify current. BC is an NPN bi-polar junction transistor.

Interface GPS with Arduino. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

It can amplify power, voltage adtasheet current at different configurations. Arduino based GPS receiver. Choosing Motor For Robots. A Transistors acts as an Amplifier when operating in Active Region. The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves.

Amplifier modules like Audio amplifiers, signal Amplifier etc. The voltage divider is the commonly used biasing mode. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base. Complete Technical Details can be found at the datasheet give at the end of this page.
