Zener diodes act as normal rectifiers until the applied voltage reaches a certain point. At this point (the Zener voltage or avalanche voltage), the diodes conducts.
For zener diodes, they are used for voltage overload protection, to prevent other semiconductor devices from momentary voltage pulses. For voltage regulation, it is designed to operate in reverse conduction. The Zener diodes is suitable for applications including the generation of a reference voltage (e.g. for an amplifier stage), or as a voltage stabilizer for low-current applications.
Used for basic regulation functions in most electronic applications, Zener diodes offer a cheaper alternative to IC solutions. With UP TEKS's selections, you will be able to find perfect parts for your specific needs.
