12V 1W Zener Diode: An Essential Component in the Electronics Industry
Introduction to Zener Diodes
Zener diodes are an essential component in the electronics industry, providing a stable reference voltage for various electronic circuits. They are designed to operate in the reverse-biased condition, where the diode breaks down and conducts in the reverse direction when a certain voltage, known as the breakdown voltage or Zener voltage, is reached. This breakdown voltage is precisely controlled during the manufacturing process, making Zener diodes reliable voltage regulators.
