Tunnel Diode Characteristics Apparatus: Amazon.in: Industrial & Scientific . A tunnel diode is a special type of PN junction diode that shows the negative resistance between two values of forward voltage (ie, between peak point voltage and valley point voltage). Zener Diode Characteristics Apparatus (Forward & Reverse V-I characteristics) Objective : T o study forward & reverse V - I characteristics of zener diode. Tunnel diode is a type of sc diode which is capable of very fast and in microwave frequency range. You must be logged in to post a review. THE TUNNEL DIODE 1. In the current I P known as peak current is corresponding to the voltage V P, the change in current to voltage (dI/dV) ratio stays 0.If V is raised past V P the current declines. Thus, it is called Tunnel diode.
