ZENER DIODES
MELF
Cathode Mark
FEATURES
♦ Silicon Planar Power Zener Diodes
♦ For use in stabilizing and clipping circuits with high
power rating.
.205 (5.2)
.189 (4.8)
.022 (0.55)
Dimensions are in inches and (millimeters)
♦ Standard Zener voltage tolerance is ±10%. Add suf-
fix “A” for ±5% tolerance. Other Zener voltages and
tolerances are available upon request.
♦ These diodes are also available in DO-41 case with the type
designation 1N4728 … 1N4764.
