Small NPN transistors for switching and amplifying signals in Arduino, micro:bit and breadboard projects. Each pack contains 5 pcs of the type you choose, in a TO-92 through-hole package.

Select a type to see its details, and check the datasheet to confirm it suits your circuit’s voltage and current. Need the opposite polarity? See our PNP Transistor Pack (5 pcs).

Pin order is not the same on every type, so check the datasheet for your part before wiring.
