HITACHI HZ-L User Manual
HZ-L Series
Silicon Epitaxial Planar Zener Diode for Low Noise Application
ADE-208-118A(Z)
Rev 1
November 1996
Features
• Diode noise level of this series is approximately 1/3-1/10 lower than the HZ series.
• Low leakage, low zener impedance and maximum power dissipation of 400 mW are ideally suited for
stabilized power supply, etc.
• Wide spectrum from 5.2V through 38V of zener voltage provide flexible application.
