TIP120 Power Darlington Transistor
Great for whenever you need to control medium to high-power electronics such as motors, solenoids, or 1W+ LEDs. We find them so handy.
Each transistor is a general purpose amplifier, model TIP120 and has a BCE pinout. They can switch up to 60V at peak currents of 8A (not continuously, just peak!) and continuous current of 5A, with a DC gain of about 1000.
