Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. BC is an NPN bi-polar junction transistor. The value of I B should not exceed mA. The voltage divider is the commonly used biasing mode. SPI Module of Arduino. Amplifier modules like Audio amplifiers, signal Amplifier etc. 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. A transistor, stands for transfer of resistance, is commonly used to amplify current. Skip to main content. Its equivalent transistors are BC and BC Virgin Galactic — Commercial Space Flight.

This high-density System-in-Package SiP integrates controller, power switches, and support components. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. What is Web Browser. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.


It can amplify power, voltage and current at different configurations. The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves. Interface SD Card with Arduino.

Of the above types common emitter type is the popular and mostly used configuration. Choosing Battery for Robots.

BC Transistor: Pinout, Diagrams, Equivalents & Datasheet

The input signal at base is amplified and taken at the emitter. For amplification applications, the transistor is biased such that it is partly on for all input conditions. Arduino based GPS receiver. A Transistors acts as an Amplifier when operating in Active Region. When base current is removed the transistor becomes fully datasgeet, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV.

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.

In the absence of base signal, it gets completely off. ddatasheet

BC547 Datasheet, Equivalent, Cross Reference Search

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


Complete Eatasheet Details can be found at the datasheet give at the end of this page. BC is mainly used for amplification and switching purposes. It has a maximum current gain of 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.

C547 Datasheet

BC is used in common emitter configuration for amplifiers. Choosing Motor For Robots. As mentioned the biasing current should maximum of 5mA. Submitted by admin on 30 August Interface GPS with Arduino. TL — Programmable Reference Voltage. 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. For switching applications, transistor is biased so that it remains fully on if there is datasheeet signal at its base.

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