• 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
• Operating and Storage temperature: -65ºC to +175ºC
• Thermal Resistance: 250 ºC/W junction to lead at 3/8 (10 mm) lead length from body, or 310ºC/W junction to ambient when mounted on FR4 PC board (1 oz Cu) with 4 mm2 copper pads and track width 1 mm, length 25 mm
• Steady-State Power: 0.5 watts at TL < 50oC 3/8 inch (10 mm) from body or 0.48 W at TA < 25ºC when mounted on FR4 PC board as described for thermal resistance above (also see Figure1)
• Forward voltage @200 mA: 1.1 volts (maximum) for 1N957B 1N985B and 1.3 V for 1N985 1N992B
• Solder Temperatures: 260 ºC for 10 s (max)
The popular the 1N976B 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 of the 1N976B 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.
