An electrical device like this requires a reverse leakage current of 100nA @ 1V.While the device is operating, the maximum voltage - Zener (Nom) is reduced to 5.6V.For operation, diode reaches 1.5V @ 200mA at the maximum voltage - Forward (Vf).
TZMA5V6-GS08 Features
reverse leakage current of 100nA @ 1V 100nA @ 1V is the maximum voltage (Tol)
