FEATURES
Silicon Planar Zener Diodes
In Mini-MELF case especially for automatic insertion.
The Zener voltages are graded according to the
international E 24 standard. Smaller voltage
tolerances and other Zener voltages are available
upon request.
These diodes are also available in DO-35 case with the type
designation ZPD1 ... ZPD51.

NOTES:
(1) Tested with pulses t
p
= 5 ms
(2) Valid provided that electrodes are kept at ambient temperature
(3) The ZMM1 is a silicon diode operated in forward direction. Hence, the index of all parameters should be "F" instead of "Z"
