An electrical device like this requires a reverse leakage current of 10μA @ 9.9V.A maximum voltage (Tol) can be supplied if 10% is set.While the device is operating, the maximum voltage - Zener (Nom) is reduced to 13V.This device must be operated with the working test voltage set to 190mA.For operation, diode reaches 1.5V @ 2A at the maximum voltage - Forward (Vf).
1N2977A Features
reverse leakage current of 10μA @ 9.9V 10μA @ 9.9V is the maximum voltage (Tol) the working test voltage to 190mA minimal dynamic impedance is 190mA
1N2977A Applications
There are a lot of Microsemi Corporation 1N2977A applications of zener single diodes.
