Zener Diodes
Features
• Silicon Planar Power Zener Diodes.
• For use in stablilizing and clipping circuits with
high power rating.
• The Zener voltages are graded according to the
international E 24 standard. Smaller voltage toler-
ances are available upon request.
• These diodes are also available in the DO-41 case
with the type designation ZPY1 ... ZPY100.

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. For devices in glass case MELF with higher Zener voltage but same power dis-
sipation see types ZMU100 ... ZMU180
