TL — Programmable Reference Voltage. A Transistors acts as an Amplifier when operating in Active Region. 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. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. Current Drains out through emitter. 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 BC Datasheet will be useful to know its package type and dimensions.

As mentioned the biasing current should maximum of 5mA.

Of the trasnistor types common emitter type is the popular and mostly used configuration. Current flows in through collector. 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. Complete Technical Details can be found at the BC datasheet given at the end of this page.

c557b transistor

Controls the biasing of transistor. It can amplify power, voltage and current at different configurations.

When c557bb 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 26 October 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.

Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. The value of I B should not exceed mA. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. 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.

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. 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.
