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. Microsemi
also offers numerous other Zener Reference Diode products for a variety of
other voltages from 6.2 V to 200 V.

NOTES:
1. When ordering devices with tighter tolerance than specified, add a hyphenated suffix to the part number for desired tolerance,
e.g. 1N3156-2%, 1N3157A-1%, 1N3157-1-1%, etc.
2. Measured by superimposing 1.0 mA ac rms on 10 mA dc @ 25oC.
3. The maximum allowable change observed over the entire temperature range i.e., the diode voltage will not exceed the
specified mV change at any discrete temperature between the established limits.
4. Voltage measurements to be performed 15 seconds after application of dc current.
5. The 1N3154, 1N3155, 1N3156, and 1N3157 also have military qualification to MIL-PRF-19500/158 up to the JANTXV level by
adding JAN, JANTX, or JANTXV prefix to part numbers as well as “-1” suffix, e.g. JANTX1N3156-1, JANTXV1N3157-1, etc.
6. Designate Radiation Hardened devices with “RH” prefix instead of “IN”, i.e. RH3157A instead of 1N3157A.
GRAPHS
The curve shown in Figure 1 is typical of the diode series and
greatly simplifies the estimation of the Temperature Coefficient
(TC) when the diode is operated at currents other than 10mA.
EXAMPLE: A diode in this series is operated at a current of
10mA and has specified Temperature Coefficient (TC) limits of
+/-0.005%/oC. To obtain the typical Temperature Coefficient
limits for this same diode operated at a current of 7.5mA, the
new TC limits (%/oC) can be estimated using the graph in
FIGURE 1.
At a test current of 7.5mA the change in Temperature Coefficient
(TC) is approximately –0.0012%.oC. The algebraic sum of +/-
0.005%oC and –0.0012%/oC gives the new estimated limits of
+0.0038%/oC and -0.0062%/oC.

This curve in Figure 2 illustrates the change of
diode voltage arising from the effect of
impedance. It is in effect, an exploded view of
the zener operating region of the I-V
characteristic.
In conjunction with Figure 1, this curve can be
used to estimate total voltage regulation under
conditions of both varying temperature and
current.
