Frequently Asked Questions

Q: Can the 2SC1741 drive a 12V relay coil?
A: Yes, the 2SC1741 can easily switch a relay coil drawing up to 500mA. Always use a flyback diode (1N4007) in parallel with the relay coil to protect the transistor from inductive voltage spikes.

Q: What is the complementary PNP transistor for the 2SC1741?
A: The complementary PNP transistor is the 2SA872 or 2SA844, which share similar voltage and current ratings.

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