About this product
The BC550 is a low-noise NPN silicon bipolar transistor in a TO-92 package, intended for small-signal amplification and switching. It is commonly used in low-current hobby circuits, such as signal stages and switching loads up to 100 mA. Check the pin order in the datasheet before wiring, because TO-92 pinouts can differ by manufacturer.

Can the BC550 switch a relay or a motor?
Only small loads within its 100 mA collector current rating. For larger relays or motors, use a transistor or driver rated for that current, and add a flyback diode across inductive loads.
How do I wire the BC550 as a switch for an LED or a microcontroller pin?
Connect the load between the collector and the supply, the emitter to ground, and drive the base through a resistor from the microcontroller pin. Confirm the terminal order in the datasheet before soldering.
