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.
