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. Standard tolerance is +/-5%, with
1% and 2% options available. The Zener test current is only 50 uA. The metal slugs that
sandwich the die are metallurgically bonded to the silicon for high reliability. This type of
internally bonded Zener package construction is also available with high-reliabilit y u p-
screening as described in the Features section. Microsemi also offers numerous other Zener
products to meet higher and lower power applications.
