HZ…L Series
SILICON EPITAXIAL PLANER ZENER DIODES
for low noise application
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 5.2 V through 38 V of zener
voltage provide flexible application.
