Silicon Epitaxial Planar Zener Diode for Stabilized Power Supply
REJ03G0180-0300Z
(Previous: ADE-208-117B)
Rev.3.00
Mar.11.2004
Features
Low leakage, low zener impedance and maximum power dissipation of 500 mW are ideally suited for stabilized
power supply, etc.
Wide spectrum from 1.6 V through 38 V of zener voltage provide flexible application.
