ZENER DIODE 550Ohm ±5% 2μA @ 167V -55°C~175°C 2 Terminations SQ-MELF
1N4990US Overview
An electrical device like this requires a reverse leakage current of 2μA @ 167V.A maximum voltage (Tol) can be supplied if 5% is set.While the device is operating, the maximum voltage - Zener (Nom) is reduced to 220V.This device must be operated with the working test voltage set to 5mA.
1N4990US Features
reverse leakage current of 2μA @ 167V
2μA @ 167V is the maximum voltage (Tol)
the working test voltage to 5mA
minimal dynamic impedance is 5mA
1N4990US Applications
There are a lot of Semtech Corporation
1N4990US applications of zener single diodes.
