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 optionally available with an internal-metallurgical-bond option by adding a “-1” suffix as well as RoHS Compliant by adding an “e3” suffix. 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 (similar to military product)
• 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)
• RoHS Compliant devices available by adding “e3” suffix
• DO-7 glass body axial-leaded Zener equivalents are also available

APPLICATIONS / BENEFITS
• 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 1020
• Minimal capacitance (see Figure 3)
• Inherently radiation hard as described in Microsemi MicroNote 050
