PN2222 NPN Transistor 40V TO-92
Transistors are powerful little electronic switches, and we really like these NPN transistors whenever we need to control medium-power electronics such as small motors, solenoids, or IR LEDs.
This transistor is a general purpose amplifier, model PN2222 (and has a standard EBC pinout. They can switch up to 40V at peak currents of 1A (not continuously, just peak!), with a DC gain of about 100. They’re basically your garden-variety NPN, and do the job with class!
