An electrical device like this requires a reverse leakage current of 5μA @ 39V.While the device is operating, the maximum voltage - Zener (Nom) is reduced to 51V.This device must be operated with the working test voltage set to 2mA.
KDZLVTR51 Features
reverse leakage current of 5μA @ 39V 5μA @ 39V is the maximum voltage (Tol) the working test voltage to 2mA minimal dynamic impedance is 2mA
KDZLVTR51 Applications
There are a lot of ROHM Semiconductor KDZLVTR51 applications of zener single diodes.
