In this episode, Karen examines p-in joints as well as discuss just how they vary from various other kinds of typical diodes, such as schottky diodes, zener diodes, LEDs (light releasing diodes), laser diodes, as well as photodiodes. Get in touch with Karen on element14: http://bit.ly/2CD2ct4

Schottky diodes frequently look like common diodes. Unlike p-n joint diodes, Schottky diodes have a metal-semiconductor joint. Silicon diodes have a voltage decrease of around 0.7 V, however the voltage decline of Schottky diodes is in between 0.15 V and also 0.46 V. While Schottky diodes can allow some voltage leakage via in reverse, zener diodes are made to permit existing to move in both instructions. The p-n joint of zener diodes is greatly doped, just a particular voltage, the Zener voltage (Vz) can pass through without harming the diode.
