DESCRIPTION
APPEARANCE
The 1N4775 thru 1N4784A series of Zero-TC Reference Diodes provides a
selection of 8.5 V nominal voltages and temperature coefficients to as low
as 0.0005%/oC for minimal voltage change with temperature when operated
at 7.5 mA. Options for screening similar to JAN, JANTX, JANTXV, and
JANS also exist by using MQ, MX, MV or MSP respectively for part number
prefixes and high reliability screening. Microsemi also offers numerous
other Zener Reference Diode products for a variety of other voltages from
6.2 V to 200 V
DO-7
(DO-204AA)

FEATURES
APPLICATIONS / BENEFITS
•
Provides minimal voltage changes over a broad
temperature range for instrumentation and other
circuit designs requiring a voltage reference
•
•
•
•
JEDEC registered 1N4775 thru 1N4784A series
Standard reference voltage of 8.5 V +/- 5%
Internal metallurgical bonds
Options for screening in accordance with MIL-PRF-
19500 for JAN, JANTX, JANTXV, and JANS are
available by adding MQ, MX, MV, or MSP prefixes
respectively to part numbers. For example,
designate “MX1N4779A” for a JANTX, or
MV1N4784A for a JANTXV screen.
Radiation Hardened devices available by changing
the “1N” prefix to “RH”, e.g. RH4779A, RH4784A,
etc. Also consult factory for “RH” data sheet
brochure for other radiation hardened reference
diode products.

•
Temperature coefficient selections available from
0.01%/ºC to 0.0005%/ºC
Tight voltage tolerances available by adding
tolerance 1%, 2%, 3%, etc. after part number for
further identification, e.g. 1N4773A-2%, 1N4774A-
1%, 1N4769-3%, 1N4769A-1%, etc.
