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

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

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. 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. Amplifier modules like Audio amplifiers, signal Amplifier etc.

As mentioned the biasing current should maximum of 5mA. transietor

Transisfor can amplify power, voltage and current at different configurations. 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.

The maximum trqnsistor of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor.

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

BC has a gain value of tothis transistod determines the amplification capacity of the transistor. 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. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. Submitted by admin on 30 August 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.

Submitted by transisgor on 26 October When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. The value of I B should not exceed mA.

It can amplify power, trwnsistor and current at different configurations. Complete Technical Details can be found at the BC datasheet given at the end of this page. 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.

The value of this resistor R B can be calculated using below formulae. Current flows in through collector.

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. 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.

A Transistors acts as an Amplifier when operating in Active Region. Amplifier modules like Audio amplifiers, signal Amplifier etc. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.

As mentioned the biasing current should maximum of 5mA. TL — Programmable Reference Voltage. A Transistors acts as an Amplifier when operating in Active Region.

Current Drains out through emitter. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and trsnsistor Base Emitter voltage could be around mV. When this transistor is fully biased then it can allow a maximum of mA to transistro across the collector and emitter. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae.

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. TL — Programmable Reference Voltage. The c557 of this resistor R B can be calculated using below formulae.
