Complete Technical Details can be found at the datasheet give at the end of this transsistor. It can amplify power, voltage and current at different configurations. As mentioned the biasing current should maximum of 5mA.

TL — Programmable Reference Voltage. Controls the biasing of transistor. The value of this resistor R B can be calculated using below formulae. Amplifier modules like Audio amplifiers, signal Amplifier etc. BC is a PNP transistor hence the collector and emitter will be closed Forward biased when the base pin is held at ground and will be opened Reverse biased when a signal c5577 provided to base pin.

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.

Submitted by admin on 26 October Current flows in through collector. Tranwistor Transistors acts as an Amplifier when operating in Active Region. 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. Amplifier modules like Audio amplifiers, signal Amplifier etc.

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

Current Drains out through emitter. BC has a gain value of tothis value determines the amplification capacity of the transistor.

When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae.

Of the above types common emitter type is the popular and mostly used configuration. As mentioned the biasing current should maximum of 5mA. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. 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.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

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. 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. Some of the configurations used in amplifier circuits are Common emitter amplifier Common collector amplifier Common base amplifier Of the above types transistr emitter type is the popular and mostly used configuration.

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