C557 TRANSISTOR PDF

Kazitaxe When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. Submitted by admin on 30 August It can amplify power, voltage and current at different configurations. Current flows in through collector. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. Current Drains out through emitter. As mentioned the biasing current should maximum of 5mA.

Kazitaxe When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. Submitted by admin on 30 August It can amplify power, voltage and current at different configurations. Current flows in through collector. Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. Current Drains out through emitter. As mentioned the biasing current should maximum of 5mA.

Controls the biasing of transistor. 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. 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.

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

When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

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.

It can amplify power, voltage and current at different configurations. The value of I B should not exceed mA. 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.

The value of this resistor R B can be calculated using below formulae. BC is a PNP transistor hence the collector and emitter will be closed Forward biased when the c55 pin is held at ground and will be opened Reverse biased when a signal is provided to base tranzistor. 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 October BC has a gain value of tothis value determines the amplification capacity of the transistor. TL — Programmable Reference Voltage. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. 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.

Amplifier modules like Audio amplifiers, signal Amplifier etc. As mentioned the biasing current should maximum of transistir. 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. Related Articles.

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 IB should be limited to 5mA. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. 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. 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.
