ZMU100 thru ZMU180 VZ Range: 100 to 180 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 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.
