As discussed a transistor will act as an Open switch during Forward Bias datashet as a Closed switch during Reverse Bias, this biasing can be achieved by supplying the required amount of current to the base pin.

Complete Technical Details can be found at the BC datasheet given at the end of this page. Current flows in through collector. BC Transistor as switch When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.

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.

Amplifier modules like Audio amplifiers, signal Amplifier etc. When this transistor is fully biased then it can allow a maximum of mA nc557a flow across the collector and emitter. Datashet the biasing of transistor. Of the above types common emitter type is the popular and mostly used configuration. As mentioned the biasing current should maximum of 5mA.

BC is a PNP transistor hence the collector and emitter will be closed Forward datwsheet when the base pin is held at ground and will be opened Reverse biased when a signal is provided to base pin. It can amplify power, voltage and current at different configurations.

If you are designing a PCD or Perf board with this component then the following picture from the BC Datasheet will be useful to know its package type and dimensions. Submitted by admin on 26 Bc5577a When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. Current Drains out through emitter.

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

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 has a gain value of tothis value determines the amplification capacity of the transistor. 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. ratasheet

When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. A Transistors acts as an Amplifier when operating in Active Region.

The value of I B should not exceed mA. Some of the configurations used in amplifier circuits are Common emitter amplifier Common collector amplifier Common base amplifier Of the above types common emitter type dattasheet the popular and mostly used configuration.
