1N749A Overview
An electrical device such as this requires reverse leakage current of 2μA @ 1V.A voltage of 5% is considered to be the maximum that can be output (Tol).During operation, the maximum voltage - Zener (Nom) is reduced to 4.3V volts.Setting the working test voltage to 20mA is required to operate this device.As soon as the maximum voltage - Forward (Vf) is supplied, it reaches 1.5V @ 200mA V.
1N749A Features
reverse leakage current of 2μA @ 1V
2μA @ 1V is the maximum voltage (Tol)
the working test voltage to 20mA
minimal dynamic impedance is 20mA
