Product Details

BC369 PNP Darlington - High Gain Switching for Relays & Motors

The BC369 is a PNP Darlington transistor in a TO-92 package, designed to deliver very high current gain from a small through-hole footprint. Its internal two-transistor configuration lets it switch loads up to 1A while being driven by a very small base current, making it a practical choice for relay, motor and lamp driver circuits controlled by microcontrollers or logic gates.

Functions & Applications

Darlington Configuration: Provides very high current gain, so a tiny base current can switch much larger loads.
1A Collector Current: Enough headroom to directly drive small relays, motors and incandescent lamps.
Standard TO-92 Package: Through-hole, breadboard-friendly and easy to hand-solder.
PNP Polarity: Useful for high-side switching or when the load is referenced to the positive supply rail.

Frequently Asked Questions

Q: Can the BC369 drive a small 12V relay directly from a microcontroller pin?
A: Yes, thanks to its Darlington configuration it needs very little base current to switch loads up to 1A, such as a small relay coil. Use a flyback diode across the coil to protect the transistor.

Q: What is the complementary NPN part for the BC369?
A: The complementary NPN Darlington transistor is the BC370.
