Transistors are powerful little electronic switches, and when our little NPN transistors aren't power enough for your project, we have been known to use these beefy TIP122 Darlington transistors. Great for whenever you need to control medium to high-power electronics such as motors, solenoids, or 1W+ LEDs.
Each transistor is a general purpose amplifier, model TIP122 and has a BCE pinout.
Switch up to 100V at peak currents(ICP) of 8A (not continuously, just peak!).
Continuous current (IC): 5A,
DC Current Gain (hFE): 1000
