ZENER DIODES
Description
ZMU100 THRU ZMU180
ZENER DIODES
MELF
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 12 standard.
Smaller voltage tolerances are available upon request.
♦ These diodes are also available in the DO-41 case with the type designation ZPU100 … ZPU180.
