Description
ZM4728A - ZM4764A
VZ : 3.3 to 100V PD : 1W
FEATURES :
Silicon planar power zener diodes For use in stabilizing and clipping circuits with
higher power rating. Standard zener voltage tolerance is ± 5%. Other zener voltages and tolerances are
available upon request. These diodes are also available in the DO-41
case with type designation 1N4728A ... 1N4764A Pb / RoHS Free
