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.
Ratings at 25°C ambient temperature unless otherwise specified.
