Diotec ZPD18B 2811661 Zener Diodes 18V voltage regulation 500mW power rating

Diotec ZPD18B is a Zener diode featuring an 18V voltage regulation capability with a power rating of 500mW. This z diode is designed to provide voltage stabilisation by maintaining a constant voltage across its terminals once the Zener voltage is reached, making it an essential component for circuit reliability. Utilising a p-n junction, it operates as a blocking diode under reverse-bias conditions until the breakdown voltage is achieved, which then allows current to flow for effective voltage regulation. Engineers typically employ the Diotec ZPD18B in applications such as voltage reference in power supply circuits, surge suppression, and noise filtering within various electronic designs.
