1N4678UR-1 thru 1N4717UR-1 Screening in reference to Available on 500 mW SURFACE MOUNT ZENER DIODES commercial MIL-PRF-19500 versions available DESCRIPTION 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-reliability up- screening as described in the Features section. Microsemi also offers numerous other Zener products to meet higher and lower power applications. DO-213AA Package Important: For the latest information, visit our website 1N4678UR-1 thru 1N4717UR-1 MECHANICAL and PACKAGING CASE: Hermetically sealed glass DO-213AA (SOD80 or MLL34) MELF style package. TERMINALS: End caps available with tin-lead plating or RoHS compliant matte-tin plating (commercial version only). Solderable per MIL-STD-750, method 2026. POLARITY: Cathode indicated by band where diode is to be operated with the banded end positive with respect to the opposite end for Zener regulation. MARKING: The cathode is the banded end of the device. TAPE & REEL option: Standard per EIA-481-1-B (add TR suffix to part number). Consult factory for quantities. WEIGHT: 0.04 grams.
