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.
• 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
• Regulates voltage over a broad operating
    current and temperature range
• Extensive selection from 6.8 to 200 V
• Standard voltage tolerances are plus/minus 5%
    with B suffix, 10 % with A suffix identification
• Tight tolerances available in plus or minus 2%
    or 1% with C or D suffix respectively
• Flexible axial-lead mounting terminals
• Nonsensitive to ESD per MIL-STD-750 Method
• Minimal capacitance (see Figure 3)
