Frequently asked questions
What is the price of BC546 NPN General Purpose Transistor TO-92 in Egypt?
BC546 NPN General Purpose Transistor TO-92 currently costs 1.5 EGP in Egypt.
Where can I buy BC546 NPN General Purpose Transistor TO-92 in Egypt?
BC546 NPN General Purpose Transistor TO-92 is available from Circuits Electronics. Compare the offers above to find the best price.
How do I use the BC546 as a switch for an LED or relay?
Connect the emitter to ground and the load between the positive supply and the collector. Feed the base through a resistor, typically in the kilohm range for a microcontroller pin, so that the base current is enough to saturate the transistor. Keep the collector current under 100mA.
What is the complementary PNP transistor for the BC546?
The BC556 is the common PNP complement to the BC546, with a similar pinout in TO-92 packaging. It is useful in push-pull or high-side switching circuits.
