The value of I B should not exceed mA. If you are designing a PCD or Perf bc557a datasheet with this component then the following bc557a datasheet from the BC Datasheet will bc57a useful to know its package type and dimensions. As mentioned the biasing current should maximum of 5mA.

The value of this resistor R B can be calculated using below formulae. Next Article BC Transistor.

BCA Datasheet PDF – Secos Corporation.

Current flows in through collector. BC has a bc557a datasheet value of tothis value determines the amplification capacity of the transistor.


Anything more than 5mA will kill the Transistor; hence a resistor is always added in series with base pin. As discussed a transistor will act as an Open switch during Forward Bias bc557a datasheet as a Closed switch during Reverse Bias, this biasing can be achieved by supplying the bc557a datasheet amount of current to the base pin.

It can amplify bc557a datasheet, voltage and current at different configurations. Top menu About Us Advertise. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter bc557a datasheet could be around mV.

Of the above types common emitter type is the popular and mostly used configuration. Bc557a datasheet the biasing of transistor. The vc557a amount of current that could flow through the Collector bc557a datasheet is mA, hence we cannot connect loads that consume more than mA using this transistor.

A Transistors acts as an Amplifier when operating in Active Region. Top menu About Us Contact. BC is a PNP transistor hence the collector and datashdet will be closed Forward biased when bc557a datasheet base pin is held at bc557a datasheet and will be opened Reverse 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. Current Drains out through emitter.

BC557A Datasheet

To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. 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 bc557a datasheet allow a maximum of mA to flow across the collector and emitter. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Bc557a datasheet as explained above.
