MIL-PRF-19500
available
The 1N4678UR-1 thru 1N4717UR-1 series of 0.5 watt glass surface mount DO-213AA Zener
voltage regulators provides a selection from 1.8 to 43 volts in standard 5% tolerances as well
as tighter tolerances with a very low test current of 50 µA. These have an internal
metallurgical bond. This type of internally bonded Zener package construction is also
available with high-reliability up-screening as described in the Features section. Microsemi
also offers numerous other Zener products to meet higher and lower power applications.
