The value of I B should not exceed mA. The value of this resistor R B can be calculated using below formulae. 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.

For switching applications, transistor is biased so that it remains fully on if there is a signal at its base. As mentioned the biasing current should maximum of 5mA. This high-density System-in-Package SiP integrates controller, power switches, and support components. 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 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.

Its equivalent transistors are BC and BC The input signal at base is amplified and taken at the emitter. 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.

Of the above types common emitter type is the datasneet and mostly used configuration. BC is mainly used for amplification and switching purposes. A Transistors acts as an Amplifier when operating in Active Region. It has a maximum current gain of A transistor, stands for transfer of resistance, is commonly used to amplify current. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.
