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.
