DESCRIPTION
The popular 1N957B thru 1N992B series of 0.5 watt Zener Voltage Regulators provides a selection from 6.8 to 200 volts in standard 5% or 10% tolerances as well as tighter tolerances identified by different suffix letters 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. The 1N962B-1 thru 1N992B-1 are available in JAN, JANTX, and JANTXV military qualifications. Microsemi also offers numerous other Zener products to meet higher and lower power applications.

FEATURES
• JEDEC registered 1N957B(-1) to 1N992B(-1) series
• Internal metallurgical bond option available by adding a “-1” suffix
• Also available in JAN, JANTX, and JANTXV qualifications per MIL-PRF-19500/117 by adding the  JAN, JANTX, or JANTXV prefixes to part numbers for desired level of screening as well as “-1” suffix; (e.g. JANTX1N962B-1, JANTXV1N986C-1, etc.)
• Military Surface Mount equivalents also available in DO-213AA by adding a UR-1 suffix in addition to the  JAN, JANTX, and JANTXV prefix; e.g. JANTX1N962BUR-1 (see separate data sheet)
• Commercial Surface Mount equivalents available as MLL957B to MLL992B or with “-1” suffix for bonded in the DO-213AA MELF style package (consult factory for others)
• DO-7 glass body axial-leaded Zener equivalents are also available
