Frequently asked questions
What is the price of BC857B PNP Bipolar Transistor 45V 100mA SOT-23 in Egypt?
BC857B PNP Bipolar Transistor 45V 100mA SOT-23 currently costs 3.5 EGP in Egypt.
Where can I buy BC857B PNP Bipolar Transistor 45V 100mA SOT-23 in Egypt?
BC857B PNP Bipolar Transistor 45V 100mA SOT-23 is available from Makers Electronics. Compare the offers above to find the best price.
What is the pin order in the SOT-23 package?
For the BC857 family in SOT-23, pin 1 is base, pin 2 is emitter and pin 3 is collector. Confirm this against the manufacturer datasheet before soldering.
Can it drive a relay or motor directly?
Only small loads at or below 100 mA. For a PNP transistor, the emitter connects to the positive supply. Use a transistor with a higher current rating or a driver for larger loads, and add a flyback diode for inductive loads such as relay coils.
