Vishay Semiconductors
Zener Diodes
Features
• Silicon Planar Power Zener Diodes.
• For use in stablilizing and clipping circuits with
high power rating.
• The Zener voltages are graded according to the
international E 24 standard. Smaller voltage toler-
ances are available upon request.
• These diodes are also available in the DO-41 case
with the type designation ZPY1 ... ZPY100.
