ZENER DIODE 50Ohm ±5% 2μA @ 51.7V -55°C~175°C 2 Terminations Axial
1N4978 Overview
The reverse leakage current needed to power this electric device is 2μA @ 51.7V.Zener single diode is a maximum voltage (Tol) that can be supplied at 5%.As part of the operation, the maximum voltage - Zener (Nom) is reduced to 68V.Setting the working test voltage to 20mA will allow this device to operate.When the voltage (Temp Coeff) reaches diodes peak, diode reaches 68mV/°C.
1N4978 Features
reverse leakage current of 2μA @ 51.7V
2μA @ 51.7V is the maximum voltage (Tol)
the working test voltage to 20mA
minimal dynamic impedance is 20mA
1N4978 Applications
There are a lot of Semtech Corporation
1N4978 applications of zener single diodes.
