1N4728 THRU 1N4764
ZENER DIODES
FEATURES
currency1 Silicon Planar Power Zener Diodes
currency1 For use in stabilizing and clipping circuits with
high power rating.
currency1 Standard Zener voltage tolerance is ±10%. Add
suffix “A” for ±5% tolerance. Other Zener voltages and
tolerances are available upon request.
currency1 These diodes are also available in the MELF case with type
designation ZM4728 thru ZM4764
