So, there’s just a wire that connects it to the anode terminal through the post lead frame. But the semiconductor P-type region is placed at the top. The semiconductor N-type region is placed at the bottom so it’s connected to the cathode terminal through Anvil lead frame. LED has three different methods to identify its terminals. These are one is positive or anode and another one is negative or cathode.

Light Emitting Diode or LED Pinout or Pin Diagram When the current flow in the forward direction then LED releases energy in the form of photons. The LED or Light Emitting Diode allows the flow of current in the forward direction and blocks the current in the reverse direction. The Light Emitting Diode is a special type of p-n junction diode which is made of special type doped semiconductor materials. The word LED meaning or LED full form is Light Emitting Diode. The LED is a two-terminal semiconductor light source that emits light when current flows through it. Construction of LED or Light Emitting Diode.
