Case: DO-41 Glass Case
Weight: approx. 0.35 g
Silicon Planar Power Zener Diodes
For use in stabilizing and clipping circuits with
high power rating.
Standard Zener voltage tolerance is ±10%. Add
suffix “A” for ±5% tolerance. Other Zener voltages and
tolerances are available upon request.
These diodes are also available in the MELF case with type
designation ZM4728 thru ZM4764
