DESCRIPTION
APPEARANCE
The popular 1N3154 thru 1N3157A series of Zero-TC Reference Diodes
provides a selection of 8.4 V nominal voltages and temperature coefficients to
as low as 0.001 %/oC for minimal voltage change with temperature when
operated at 10.0 mA. These glass axial-leaded DO-7 reference diodes are
also available in JAN, JANTX, and JANTXV military qualifications. As a further
option for commercial product, they are available as RoHS Compliant with an
e3 suffix added to the part number. 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)

For instrumentation and other circuit designs
requiring a stable voltage reference
•
1N3154, 3155, 3156, and 3157 also have military
qualification to MIL-PRF-19500/158 up to the
JANTXV level by adding JAN, JANTX, or JANTXV
prefixes to part numbers as well as “-1” suffix, e.g.
JANTX1N3157-1, etc.
Maximum temperature coefficient selections
available from 0.01%/ºC to 0.001%/ºC
Tight reference voltage tolerances at the 8.4 V
nominal is available by adding tolerance 1%, 2%,
3%, etc. after the part number for identification e.g.
1N3156-2%, 1N3157A-1%, 1N3157-1-1%, etc.
