Submitted by admin on 30 August When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. BC has a gain value of tothis value determines the amplification capacity of the transistor.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. The input signal at base is amplified and taken at the emitter. As mentioned the biasing current should maximum of 5mA.

A Transistors acts as an Amplifier when operating in Active Region. 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.

Skip to main content. It has a maximum current gain of Amplifier modules like Audio amplifiers, signal Amplifier etc. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin.


For amplification applications, the transistor is biased such that it is partly on for all input conditions. 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.

To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. It can amplify power, voltage and current at different configurations. BC is used in common emitter configuration for amplifiers. 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.

The value of I B should not exceed mA. 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 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. A transistor, stands for transfer of resistance, is commonly used to amplify current. Arduino based GPS receiver. Choosing Battery for Robots.


Choosing Motor For Robots. The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves. BC is mainly used for amplification and switching purposes. BC is an NPN bi-polar junction transistor.

In the absence of base signal, it gets completely off. What is Web Browser. 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.
