Frequently asked questions
What is the price of BC558 PNP Bipolar Transistor 30V 100mA TO-92 in Egypt?
BC558 PNP Bipolar Transistor 30V 100mA TO-92 currently costs between 0.75 and 2 EGP across 3 offers in Egypt.
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, Microohm, 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.
