1N4678UR-1 thru 1N4717UR-1 Available on commercial versions 500 mW SURFACE MOUNT ZENER DIODES Screening in reference to MIL-PRF-19500 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 in standard 5% tolerances as well as tighter tolerances with a very low test current of 50 A. 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. DO-213AA Package Important: For the latest information, visit our website http://www.microsemi.com.
