About This Article
Descriptions
Tantalum electrochemical diode has been developed. It consists of tantalum needle (anode) having an oxidized film metamorphosed by heating treatment, carbon electrode (cathode) and electrolyte (4%(v/v)H_2SO_4 solution). Maximum applicable reverse voltage of tantalum diode is 300 volts and reverse leakage current of tantalum diode is less than a micro-ampere when applied reverse voltage is below 35 volts. It works as a good diode when the frequency of input signal is below 100 KC. Temperature dependence of tantalum diode is obtained experimentally.
