ZMM1...ZMM75
Silicon Epitaxial Planar Zener Diodes
in MiniMELF case especially for automatic insertion.
The Zener voltages are graded according to the
international E24 standard. Smaller voltage tolerances
and higher Zener voltages are upon request.
LL-34
These diodes are also available in DO-35 case with
the type designation BZX55C...

The ZMM1 is a silicon diode with operation in forward direction. Hence, the index of all parameters should be "F" instead of "Z". Connect the cathode
electrode to the negative pole.
