Frequently Asked Questions

Q: Can the 2N2905 drive a 12V relay?
A: Yes. The 600mA collector current rating is more than sufficient to drive most electromagnetic relay coils. Always use a flyback diode in parallel with the relay coil to protect the transistor from inductive voltage spikes.

Q: What is the complementary NPN transistor for the 2N2905?
A: The complementary NPN transistor is the 2N2906, offering equivalent voltage and current ratings but with opposite polarity.

Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
