12.8 Volt LOW NOISE TEMPERATURE
COMPENSATED ZENER REFERENCE DIODES
DESCRIPTION
The 1N4896(A) through 1N4915(A) series provides a selection of temperature compensated
12.8 V (nominal) Zener diodes. The voltage tolerace is +/- 5% and the "A" version of the parts
in this series have an expanded low temperature range down to -55 oC. Microsemi also offers
numerous other Zener reference diode products for a variety of other voltages.

FEATURES
• JEDEC registered 1N4896 thru 1N4915 series.
• 12.8 volt nominal Zener voltage +/- 5%.
• Temperature Coefficient range: 0.01 %/oC to 0.001%/oC.
• Metallurgically bonded.
• Double plug construction.
• RoHS compliant versions available.
APPLICATIONS / BENEFITS
• Provides minimal voltage changes over a broad temperature range.
• For instrumentation and other circuit designs requiring a stable voltage reference.
• Low noise.
• Flexible axial-lead mounting terminals.
• Non-sensitive to ESD per MIL-STD-750 method 1020.

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 25 oC ambient temperature. ND is calculated
from the formula.
