Transistor BC547

When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. The transistor terminals require a fixed DC voltage to operate in the desired region datashfet its characteristic curves. This is known as the biasing. Interface SD Card with Arduino. BC is used in common emitter configuration for amplifiers.

BC is an NPN bi-polar junction transistor. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base. Of the above types common emitter type is the popular and mostly used configuration.

The value of this resistor R B can be calculated using below formulae. The voltage divider is the commonly used biasing mode. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.


TL — Programmable Reference Voltage. Choosing Motor For Robots. Virgin Galactic — Commercial Space Flight. BC is mainly used for amplification and switching purposes.

Its equivalent transistors are BC and BC The value of I B should not exceed mA. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin.

What is Web Browser. The maximum amount of current that could dtasheet through c54 Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. In datasheeh absence of base signal, it gets completely off. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

A Transistors acts as an Amplifier when operating in Active Region. A transistor, stands for transfer of resistance, is commonly used to amplify current. Amplifier modules like Audio amplifiers, signal Amplifier etc. This high-density System-in-Package SiP integrates controller, power switches, and support components.

BC Transistor: Pinout, Diagrams, Equivalents & Datasheet

As mentioned the biasing current should maximum of c574. Submitted by admin on 30 August 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. Arduino based GPS receiver. Interface GPS with Arduino.

It has a maximum current gain of 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.


For amplification applications, the transistor is biased such that it is partly on for all input conditions. The input signal at base is amplified and taken at the emitter. Skip to main content.

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. BC has a gain value of tothis value determines the amplification capacity of the transistor. SPI Module of Arduino. It can amplify power, voltage and current at different configurations. Complete Technical Details can be found at the datasheet give at the end of this page. 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.

When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. Choosing Battery v547 Robots.
