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 TIP120 Darlington transistors. Great for whenever you need to control medium to high-power electronics such as motors, solenoids, or 1W+ LEDs. We find them so handy, they come in a pack of 3!
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. For more details, check the datasheet.
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
