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.
