An electrical device like this requires a reverse leakage current of 200nA @ 11V.While the device is operating, the maximum voltage - Zener (Nom) is reduced to 15V.This device must be operated with the working test voltage set to 10mA.
TFZVTR15B Features
reverse leakage current of 200nA @ 11V 200nA @ 11V is the maximum voltage (Tol) the working test voltage to 10mA minimal dynamic impedance is 10mA
TFZVTR15B Applications
There are a lot of ROHM Semiconductor TFZVTR15B applications of zener single diodes.
