FEATURES
♦ Silicon Planar Power Zener Diodes
♦ For use in stabilizing and clipping circuits with higher
power rating.
♦ The Zener voltages are graded according to the
international E24 standard. Smaller voltage tolerances
and other Zener voltages are available upon request.
♦ These diodes are also available in the DO-41 case with the type
designation ZPY1 … ZPY100.

NOTES:
(1) Valid provided that electrodes are kept at ambient temperature
(2) Tested with pulses t
p
= 5 ms
(3) The ZMY1 is a silicon diode operated in forward direction. Hence, the index of all characteristics and maximum ratings should be “F” instead of “Z”.
Connect the cathode terminal to the negative pole
