ZENER DIODES
FEATURES
DO-41 Glass

♦ Silicon Planar Power Zener Diodes ♦ For use in stabilizing and clipping circuits with high power rating. ♦ Standard Zener voltagetolerance 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 thruZM4764
