Submitted by admin on 26 October When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae.

BC is a PNP transistor hence the collector and emitter will be closed Gc157 biased when the base pin is held at ground and will be opened Reverse biased when a signal is provided to base pin.

Nc157 bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.

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 is the popular and mostly used configuration. Of the above types common emitter type is the datasgeet and mostly used configuration.

The value of this resistor R B can be calculated using below formulae. 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. It can amplify power, voltage and current at different configurations. BC has a gain value of tothis value determines the amplification capacity of the transistor.

Controls the biasing of transistor. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. A Transistors acts as an Amplifier when operating in Active Region.

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

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. If you are designing a PCD or Perf board with this dxtasheet then the following picture from the BC Datasheet will be useful to know its package type and dimensions.

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. Current flows in through collector.

As mentioned the biasing current should maximum of 5mA. The value of I B should not exceed mA.

Amplifier modules like Audio amplifiers, signal Amplifier etc. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.

TL — Programmable Reference Voltage. Current Drains out through emitter. 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 datasheeet required amount of current to the base pin.
