3mm Red DIP LED | Through Hole Dip LED

It's a red DIP LED with a diameter of 3mm. When triggered, an LED is a two-lead semiconductor device that generates light. When a suitable voltage is given to the LED terminal, the electrons within the device are enabled to rejoin with the electron holes and produce power in the form of photons. Electroluminescence is the name for this phenomenon. The energy bandgap of the semiconductor determines the colour of the LED.
