This is the central component in a clamper circuit, which shifts a potential difference average so that it is not zero.  
This is the central component in a clamper circuit, which shifts a potential difference average so that it is not zero.  The first semiconductor type of this was known as a "cat's whisker" and used in early radios. The type containing a metal–semiconductor junction can be combined with a transistor and is named for Walter Schottky. These are a type of rectifier, sometimes classified as the ones used with low power. The avalanche type is similar to the Zener type in that they both have a breakdown voltage beyond which backward current occurs, and some calculators use the light-emitting type. Name these devices that ideally are supposed to completely allow current in one direction but stop it in the opposite direction.
