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 8.5V volts.Setting the working test voltage to 1mA is required to operate this device.0.85mV/°C is reached once the voltage is at its maximum (Temp Coeff).
1N4780A Features
the working test voltage to 1mA minimal dynamic impedance is 1mA
1N4780A Applications
There are a lot of Microsemi Corporation 1N4780A applications of zener single diodes.
