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 @ 25

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%/

limits for this same diode operated at a current of 7.5mA, the

new TC limits (%/

FIGURE 1.

At a test current of 7.5mA the change in Temperature Coefficient

(TC) is approximately –0.0012%.
