The TIP120 is a NPN Darlington Power Transistor. It can switch loads up to 60V with a peak current of BA and continuous current of 5A. This makes it suitable for medium and high power electronics like controlling monitors, solenoids or high LEDs.
Pin configuration
| Pin Number | Pin Name | Description |
| 1 | Base | Controls the biasing of Transistor, Used to turn ON or OFF the transistor |
| 2 | Collector | Current flows in through collector, normally connected to load |
| 3 | Emitter | Current Draws out through emitter, normally connected to ground |
