Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin.

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. Complete Technical Details can be found at the datasheet give at the end of this page.

When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. The value of I B should not exceed mA.


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. It can amplify power, voltage and current at different configurations. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using datqsheet below formulae.

A Transistors acts as an Amplifier when operating in Active Region. The maximum amount of datasheef that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor.

As discussed a transistor will act as an Open switch during Catasheet 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. 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. The value of this resistor R B can be calculated using below formulae.

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 mentioned the biasing current should maximum of 5mA. Amplifier modules like Audio amplifiers, signal Amplifier etc.
