When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. 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 transiztor. When base current is removed the transistor becomes fully off, datashheet stage is called as the Cut-off Region and the Base Emitter voltage could be around mV.

A transistor, stands for transfer of resistance, is commonly used to amplify current. BC is used in common emitter configuration for amplifiers.

Interface SD Card with Arduino. BC is an NPN bi-polar junction transistor.

Interface GPS with Arduino. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. Submitted by admin on 30 August Choosing Battery for Robots. Complete Technical Details can be found at the datasheet give at the end of this page.


For amplification applications, the transistor is biased such that it is partly on for all input conditions. BC is mainly used for amplification and switching purposes. Of the above types common emitter type is the popular and mostly used configuration. As mentioned the biasing current should maximum of 5mA. Virgin Galactic — Commercial Space Flight. 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.

To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. What is Web Browser. The value of I B should not exceed mA.

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 Forward biased when a signal is provided to base pin.

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 transistot amount of current to the base pin.

Its equivalent transistors are BC and BC The input signal at base is amplified and taken at the emitter.


The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves. A Transistors acts as an Amplifier when operating in Active Region. It can amplify power, voltage and current at different configurations.

This is known as the biasing. Skip to main content. The value of this resistor R B can be calculated using below formulae.

Transistor BC547

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. This high-density System-in-Package SiP integrates controller, power switches, and support components.

TL — Programmable Reference Voltage.

BC has a gain value of tothis value determines the amplification capacity of the transistor. Arduino based GPS receiver. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.

Amplifier modules like Audio amplifiers, signal Amplifier etc. Bc47 Module of Arduino. Choosing Motor For Robots.

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. It has a maximum current gain of
