When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. As mentioned the biasing current should maximum of 5mA. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

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. It can amplify power, voltage and current at different configurations. The value datasbeet this resistor R B can be calculated using below formulae.


The value of I B should not exceed mA. 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 datasheeg transistor.

c547 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.

Submitted by admin on 30 August A Transistors acts as an Amplifier when operating in Active Region. 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.

TL — Programmable Reference Voltage. Amplifier modules like Audio amplifiers, signal Amplifier etc. BC has a gain value of tothis value determines the amplification capacity of the transistor.

Complete Technical Details can be found at the datasheet give at the end of this page. 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 F547b the DC current gain of the Transistor can be calculated by using the below formulae.

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 dafasheet dimensions. Of the above types common emitter type is the popular and mostly used configuration. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin.
