ZMY1 thru ZMY100
V
Z
Range: 1.0, 3.9 to 100 Volts
Zener Diodes
Power Dissipation: 1.0W
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
E 24 standard. Smaller voltage tolerances 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
=5ms
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
For devices in glass case MELF with higher Zener voltage but same power dissipation see types ZMU100 ... ZMU180
