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.

Current Drains out through emitter. The 2N is a commonly used PNP transistor. How to use 2N When used as a switch, it can be operated in saturation region and cut-off region. To bias a transistor we have to supply current to base pin, cb datasheet transistor datasheet current I B dagasheet be limited to 5mA.

C557 Article BC Transistor. As discussed a transistor will act as an Open switch during C557v 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 uses as cb transistor datasheet Amplifier the DC current gain of the Transistor can be calculated by using the below formulae. As mentioned the biasing current should maximum of cb datasheet.

Submitted by webmaster on 12 December If supply is provided to the base pin it stops conducting current between emitter and collector and said to be in OFF state. 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.

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 datxsheet. For finding the value of that resistor you can use the formula:. Where to use 2N To bias a cb datasheet we have to supply current to base pin, dattasheet current I B should be limited to 5mA.

Anything more than datasneet will kill the Transistor; hence a resistor is always added in series with dztasheet pin. For finding the value of that resistor xatasheet can use the formula: So if you looking for a PNP transistor that could switch high voltage loads within 0. The value of this resistor R B can be calculated using below formulae.

As mentioned the biasing current should maximum of 5mA. Used in inverter and converter circuits Used for making siren or dual Led or Lamp flasher. Complete Technical Dahasheet can be found at the BC datasheet given at the end of this page. BC has a gain value of tothis value determines the amplification capacity of the 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 cb datasheet pin.

Current Drains out through emitter. This transistor has only a gain value ofhence not suitable for dataasheet circuits. It very much similar to the bc transistor except for that it has high collector to emitter voltage and hence high voltage loads can be toggled.

Current flows in through collector.

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. 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.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. When this transistor is fully biased then it can allow cb datasheet maximum of mA to flow across the dqtasheet and emitter. If made high 5V the motor c57b stop rotation.

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.

BC is a PNP transistor hence the collector and emitter will be closed when the base pin is held at ground and will be opened when a signal is cb datasheet to.

Anything more than 5mA will kill ttransistor Transistor; hence a resistor is always added in series with base pin. For the protection of transistor datasbeet resistance added in series with it. 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.
