Adafruit Bipolar Transistor Kit - 5 x PN2222 NPN and 5 x PN2907 PNP

Transistors are powerful little electronic switches, and these NPN and PNP transistors are perfect for controlling medium-power electronics such as small motors, solenoids, or IR LEDs. This mix-and-match bag includes 5 x NPN and 5 x PNP, ideal for projects like class B amplifiers, or handling high or low side control.

Each transistor serves as a general-purpose amplifier with a standard EBC pinout. PN2222 transistors switch up to 40V at 1A peak, with a DC gain of about 100, similar to the 2N3904. The PN2907 transistors handle up to 60V at 600 mA peak with similar gain, making them ubiquitous but effective bipolar transistors.
