FEATURES
Silicon Planar Zener Diodes
The Zener voltages are graded according to
the international E 12 standard. Smaller voltage
tolerances and other Zener voltages are available
upon request.
These diodes are also available in the Mini-MELF case
with the type designation ZMM1 ... ZMM75.

NOTES:
(1) Tested with pulses t
p
= 5 ms
(2) Valid provided that leads at a distance of 4 mm from case are kept at ambient temperature
(3) The ZPD1 is a silicon diode operated in forward direction. Hence, the subscript of all parameters should be "F" instead of "Z".
