Where can I buy BC558 PNP Bipolar Transistor 30V 100mA TO-92 in Egypt?
BC558 PNP Bipolar Transistor 30V 100mA TO-92 is available from Makers Electronics, RAM Electronics, Most Electronics, Microohm, Circuits Electronics, and Future Electronics. Compare the offers above to find the best price.
What is the pin order of the BC558?
The listing gives pin 1 as collector, pin 2 as base and pin 3 as emitter. TO-92 pin order depends on which side of the package faces you, so confirm the orientation against the datasheet before wiring.
How do I use it as a switch with a microcontroller?
As a PNP, it is typically used as a high-side switch: the emitter goes to the positive supply and the load is on the collector side. The base is driven through a resistor, and the transistor turns on when the base is pulled low relative to the emitter.
