This popular series of 500 mW Zener voltage regulators provides a selection from 2.4 to 12 volts in a standard 5% tolerance as well as available tighter 2% and 1% tolerances. These axial-leaded, glass DO-35 Zeners feature an internal metallurgical bond and are military qualified to the JAN, JANTX, and JANTXV level. A RoHS compliant commercial grade only version is also available.
DESCRIPTION The popular 1N746 thru 1N759A and 1N4370 thru 1N4372A series of 0.5 watt Zener Voltage Regulators provides a selection from 2.4 to 12 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. These are also 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 1N746 thru 1N759A and 1N4370 thru 1N4372A series • Internal metallurgical bond option available by adding a “-1” suffix • Also available in JAN, JANTX, and JANTXV qualifications per MIL-PRF-19500/127 by adding the JAN, JANTX, or JANTXV prefixes to part numbers for desired level of screening as well as –1” suffix; (e.g. JANTX1N751A-1, JANTXV1N758C-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 MLL746 to MLL759A and MLL4370 to MLL4372A including the “-1” suffix in the DO-213AA MELF style package (consult factory for others) • DO-7 glass body axial-leaded Zener equivalents are also available APPLICATIONS / BENEFITS • Regulates voltage over a broad operating current and temperature range • Selection from 2.4 to 12 V • Standard voltage tolerances are plus/minus 5% with A suffix identification and 10 % with no suffix • 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
