HZS Series
Silicon Epitaxial Planar Zener Diode for Stabilized Power Supply
ADE-208-120A(Z)
Rev 1
Features
• Low leakage, low zener impedance and maximum power dissipation of 400 mW are ideally suited for
stabilized power supply, etc.
• Wide spectrum from 1.5V through 38V of zener voltage provide flexible application.
• Suitable for 5mm-pitch high speed automatic insertion.
