SEMTECH ELECTRONICS LTD.

ZMM…L Series
Silicon Epitaxial Planar Zener Diodes
LL-34
Features
• Low leakage, low zener impedance and maximum
power dissipation of 500 mW are ideally suited for
stabilized power supply, etc.
• Wide spectrum from 5.2 V through 38 V of zener
voltage provide flexible application.
