Frequently Asked Questions

Q: Can the BC547 drive a 12V relay?
A: Yes, as long as the relay's coil current is below 100mA (Ic). Always use a flyback diode to protect the transistor from inductive spikes.

Q: What is the complementary PNP part for BC547?
A: The complementary PNP transistor is the BC557.
