An electrical device like this requires a reverse leakage current of 250nA @ 128V.A maximum voltage (Tol) can be supplied if 1% is set.While the device is operating, the maximum voltage - Zener (Nom) is reduced to 160V.This device must be operated with the working test voltage set to 1.6mA.For operation, diode reaches 1V @ 200mA at the maximum voltage - Forward (Vf).
JAN1N4494D Features
reverse leakage current of 250nA @ 128V 250nA @ 128V is the maximum voltage (Tol) the working test voltage to 1.6mA minimal dynamic impedance is 1.6mA
