Zener Diode Information

Zener diodes are diodes that have a specified voltage drop when in reverse bias. Some useful facts about zener diodes are:

  1. Zener doides can range from 2.4V to 200V and 1/4W to 50W.
  2. Some applications for zener diodes are voltage references, voltage regulators, transient protection, and RF clamps.
  3. Zener diodes rated at over 1W usually come in stud mount packages. They also can have haet sinks to dissipate heat away from the junction.
  4. To identify a zener diode one must read the value off the component or find the part number or the manufacturers number.
