Abstract
A vehicle alternator output rectifier instrument in which mesa structure Zener diodes, formed by diffusion of impurity on a P-type silicon substrate, are used as rectifier elements which are used in rectifier circuits for rectifying an alternate current output of a vehicle alternator. Since the vehicle alternator output rectifier instrument employs the above Zener diodes, this rectifier instrument can endure high temperature circumstances, considerably reduce a reverse leakage current to thereby prevent a battery voltage from being discharged and reduce a radio noise to thereby reduce a bad influence exerted upon an electronic device serving as a load.
