How to use BC559

Because transistors are current-controlled devices, a small amount of current is required to switch them on and off. This current is less than 2mA for the BC556 Transistor since it is a PNP transistor, which means it is on when the base is connected to the ground and off when a positive voltage is provided to the transistor's base.

The simulated circuit below shows how this transistor operates when the basic circuit's base is connected to the ground and when the power supply's 5V is applied.

Frequently Asked Questions

How does BC559 work?
The BC559 transistor is a PNP transistor that can be used for a variety of applications. A doped N-Type material is sandwiched between two P-Type materials to form a PNP transistor. In a PNP transistor, the majority charge carrier is holes, which are emitted by the collector and collected by the emitter. The main difference between an NPN and a PNP transistor is that in an NPN transistor, electrons flow from collector to emitter, whereas in a PNP transistor, electrons flow from emitter to collector. As a result, a PNP transistor turns on when the base voltage is low or 0V. When a positive or high signal is applied, an NPN transistor is turned on.
How to use BC559 in safe?
Use the transistor at 20% of its maximum rating for safe operation. The maximum collector current is -100mA, so don't drive loads higher than 80mA; the maximum collector-emitter voltage is -30, so don't drive loads higher than -24V; and always store and operate this transistor at temperatures between -65 and +150 degrees Celsius.
What package is BC559 available in?
It is available in a TO-92 Package.
