An electrical device like this requires a reverse leakage current of 200nA @ 23V.While the device is operating, the maximum voltage - Zener (Nom) is reduced to 30V.This device must be operated with the working test voltage set to 5mA.
TFZVTR30B Features
reverse leakage current of 200nA @ 23V 200nA @ 23V is the maximum voltage (Tol) the working test voltage to 5mA minimal dynamic impedance is 5mA
TFZVTR30B Applications
There are a lot of ROHM Semiconductor TFZVTR30B applications of zener single diodes.
