DESCRIPTION
The 1N5728 thru 1N5757 series of 0.5 watt Zener Voltage Regulators provides a selection from 4.7 to 75 volts in standard 5% tolerances as well as tighter tolerances identified by a “C” or “D” suffix letter on the part number. These glass axial-leaded DO-35 Zeners are also available with an internal-metallurgical-bond option by adding a “-1” suffix. Microsemi also offers numerous other Zener products to meet higher and lower power applications.

FEATURES
• JEDEC registered 1N5728 to 1N5757 series
• Internal metallurgical bond option available by adding a “-1” suffix
• Options for screening in accordance with MIL-PRF-19500 for JAN, JANTX, JANTXV, and JANS are available by adding MQ, MX, MV, or MSP prefixes respectively to part numbers with “-1” suffix
• Surface Mount equivalents are also available in DO-213AA by adding a UR or UR-1 suffix, e.g. 1N5728UR, 1N5746UR-1, etc. (see separate data sheets)
• DO-7 glass body axial-leaded Zener equivalents are also available
