StandardZenerdioden

StandardZenerdioden are a specific type of diode designed to operate in the reverse breakdown region. Unlike standard diodes which are meant to block current in reverse bias, Zener diodes are engineered to maintain a constant voltage across them once a certain reverse voltage, known as the Zener voltage (Vz), is reached. This characteristic makes them useful for voltage regulation.

The operation of a Zener diode relies on the Zener effect or avalanche breakdown. When the reverse voltage applied exceeds the Zener voltage, the diode enters a state of rapid current increase while maintaining a relatively stable voltage. This stable voltage is a key feature. The power dissipation within the diode must be considered, as it is inversely proportional to the Zener voltage for a given current.

StandardZenerdioden are available in a wide range of Zener voltages, from a few volts up to hundreds of volts. They are typically used in circuits where a stable reference voltage is required or to protect sensitive components from overvoltage conditions. Their low cost and simplicity contribute to their widespread use in electronics. When selecting a Zener diode, important parameters include the Zener voltage, power rating, and tolerance.
