ZMU150

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.
