2. Zener diode - Wikipedia

   en.wikipedia.org/wiki/Zener_diode

   A Zener diode is a special type of diode designed to reliably allow current to flow "backwards" (inverted polarity) when a certain set reverse voltage, known as the Zener voltage, is reached. Zener diodes are manufactured with a great variety of Zener voltages and some are even variable.

   en.wikipedia.org/wiki/File:Zener_diode_symbol.svg

   English: The circuit diagram symbol for a Zener diode. When used in a circuit diagram, the words "Anode" and "Cathode" are not included with the graphic symbol. (Revised to conform to ANSI Y32.2-1975 and IEEE-Std. 315-1975.)

4. Diode - Wikipedia

   en.wikipedia.org/wiki/Diode

   The symbol used to represent a particular type of diode in a circuit diagram conveys the general electrical function to the reader. There are alternative symbols for some types of diodes, though the differences are minor. The triangle in the symbols points to the forward direction, i.e. in the direction of conventional current flow.

   en.wikipedia.org/wiki/Electronic_symbol

   An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...

9. Current source - Wikipedia

   en.wikipedia.org/wiki/Current_source

   A Zener diode, when reverse biased (as shown in the circuit) has a constant voltage drop across it irrespective of the current flowing through it. Thus, as long as the Zener current (I Z) is above a certain level (called holding current), the voltage across the Zener diode (V Z) will be constant.
