GRAPHS and CIRCUIT
FIGURE 1 Noise Density Measurement Circuit
Noise density, (ND) is specified in microvolt-rms per squre-
root-hertz. Actual measurement is performed using a 1 KHz
to 3 KHz frequency bandpass filter at a constant Zener test
current (IZT) AT 25oC ambient temperature. ND is calculated
from the formula.

DESCRIPTION
The 1N4099UR thru 1N4135UR and 1N4614UR thru 1N4627UR series of 0.5 watt glass surface mount DO-213AA Zener voltage regulators provides a selection from 1.8 to 100 volts in standard 5% tolerances as well as tighter tolerances identified by different suffix letters on the part number. These are also available with an internal-metallurgical-bond option by adding a “-1” suffix (see separate data sheet) including JAN, JANTX, and JANTXV military qualifications. Microsemi also offers numerous other Zener products to meet higher and lower power applications.

FEATURES
• Surface mount equivalent to JEDEC registered 1N4099 thru 1N4135 and 1N4614 thru 1N4627 series
• Internal metallurgical bond option available by adding a “-1” suffix that also includes JAN, JANTX, and JANTXV qualifications per MIL-PRF-19500/435 (see separate data sheet for same part numbers with “-1” suffix)
• DO-7 or DO-35 glass body axial-leaded Zener equivalents also available per JEDEC registration (see separate data sheet for part numbers 1N4099 thru 1N4135 and 1N4614 thru 1N4627 series

APPLICATIONS / BENEFITS
• Regulates voltage over a broad operating current and temperature range
• Extensive selection from 1.8 to 100 V
• Standard voltage tolerances are plus/minus 5% with no suffix
• Tight tolerances available in plus or minus 2% or 1% with C or D suffix respectively
• Hermetically sealed surface mount package
• Nonsensitive to ESD per MIL-STD-750 Method 1020
• Minimal capacitance (see Figure 3)
• Inherently radiation hard as described in Microsemi MicroNote 050
