Submitted by admin on 26 October It can amplify power, voltage and current at different configurations. Anything dztasheet than 5mA will kill the Transistor; hence a resistor is always added in series with base pin.
Amplifier modules like Audio amplifiers, signal Amplifier etc. The value of this resistor R B can be calculated using below formulae.
Complete Technical Details can be found at the BC datasheet given at the end of this page. The value of I B should datashheet exceed mA. When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. Some of the configurations used in amplifier circuits are Common emitter amplifier Common collector amplifier Common datasjeet amplifier Of the above types common emitter type is the popular and mostly used configuration.
BC Transistor Pinout, Description, Equivalent & Datasheet
TL — Programmable Reference Voltage. Current Drains out through emitter.
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. BC is a PNP transistor hence the collector and emitter will datashset 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.
Controls the biasing of transistor.
Current flows in through collector. Datashert 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. 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. BC has a gain value of tothis value determines the amplification capacity of the transistor. 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. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.
To bias a transistor we have to supply current to base bf557a, this current I B should be limited to 5mA.
A Transistors acts as an Amplifier when operating in Active Region. As mentioned the biasing current should maximum of 5mA.
