Description
1N746AUR-1 – 1N759AUR-1, 1N4370AUR-1 – 1N4372AUR-1
Available on commercial
versions
Silicon MELF 500 mW Zener Diodes
Qualified per MIL-PRF-19500/127
DESCRIPTION
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 glass, surface mount DO-213AA 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.
Qualified Levels: JAN, JANTX, and
JANTXV

FEATURES
• JEDEC registered 1N746 through 1N759A and 1N4370 through 1N4372A series.
• Standard voltage tolerance is ± 5% with optional tighter tolerances of ± 2% or 1%.
• Internal metallurgical bond.
• JAN, JANTX, and JANTXV qualifications are available per MIL-PRF-19500/127.
(See part nomenclature for all available options.
) • RoHS compliant versions available (commercial grade only).
• These commercial surface mount equivalents were also previously identified with a CDLL or MLL
prefix instead of the "1N" prefix.
APPLICATIONS / BENEFITS
• Regulates voltage over a broad range of temperature and current.
• Regulated voltage range from 2.
4 to 12 V.
• Small size for high density mounting using the surface mount method (see package illustration).
• Non-sensitive to ESD per MIL-STD-750 method 1020.
• Minimal capacitance.
• Inherently radiation hard as described in Microsemi MicroNote 050.
