Diode schematic symbols of electronic circuit - Diode, LED, Zener diode, Schottky diode, photodiode, ...
Left - Anode, Right - Cathode.
|Diode||Diode allows current flow in one direction only (left to right).|
|Zener Diode||Allows current flow in one direction, but also can flow in the reverse direction when above breakdown voltage|
|Schottky Diode||Schottky diode is a diode with low voltage drop|
|Varactor / Varicap Diode||Variable capacitance diode|
|Light Emitting Diode (LED)||LED emits light when current flows through|
|Photodiode||Photodiode allows current flow when exposed to light|
