DESCRIPTION
Screening in
reference to
MIL-PRF-19500
available
The 1N4678-1 thru 1N4717-1 series of 0.5 watt Zener voltage regulators provides a selection
from 1.8 to 43 volts in standard 5% tolerances as well as tighter tolerances. These axial-
leaded glass DO-35 Zeners are available with an internal metallurgical bond similar to military
requirements for similar Zeners. Microsemi also offers numerous other Zener products to
meet higher and lower power applications.
