Frequently Asked Questions

Q: Is the 2SC1449 compatible with a heatsink?
A: Yes, the TO-126 package includes a mounting hole that accepts M3 or M2.5 screws, allowing secure attachment to a heatsink for improved thermal performance.

Q: Can the 2SC1449 drive a 12V relay?
A: Yes, provided the relay coil current is below 150mA (Ic). Always include a protective flyback diode (1N4148 or similar) across the relay coil to protect the transistor from inductive spikes.
