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. https://elecena.pl/product/29477200/adafruit-bipolar-transistor-kit-5-x-pn2222-npn-and-5-x-pn2907-pnp 2025-11-03 https://elecena.pl/product/29477200/adafruit-bipolar-transistor-kit-5-x-pn2222-npn-and-5-x-pn2907-pnp 2025-12-14 https://elecena.pl/product/29477200/adafruit-bipolar-transistor-kit-5-x-pn2222-npn-and-5-x-pn2907-pnp 2025-12-19 https://elecena.pl/product/29477200/adafruit-bipolar-transistor-kit-5-x-pn2222-npn-and-5-x-pn2907-pnp 2026-01-23 https://elecena.pl/product/29477200/adafruit-bipolar-transistor-kit-5-x-pn2222-npn-and-5-x-pn2907-pnp 2026-02-01 https://elecena.pl/product/29477200/adafruit-bipolar-transistor-kit-5-x-pn2222-npn-and-5-x-pn2907-pnp 2026-04-08
