*JEDEC Registered Data.
NOTES:
1. When ordering devices with tighter tolerances than specified, use a nominal voltage of 9.2V and add a hyphenated suffix
to the part number for desired tolerance at the end of the part number, e.g. 1N938B-2%, 1N939B-1%, 1N939B-1-1%, etc.
2. Measured by superimposing 0.75 mA ac rms on 7.5 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 1N935B, 937B, 938B, 939B, 940B also have military qualification to MIL-PRF-19500/156 up to the JANTXV level by
adding JAN, JANTX, or JANTXV prefixes to part numbers as well as “-1” suffix, e.g. JANTX1N938B-1, etc.
6. Designate Radiation Hardened devices with “RH” prefix instead of “IN”, i.e. RH938A instead of 1N938A.
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 7.5mA.
EXAMPLE: A diode in this series is operated at a current of
7.5mA 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 6.0mA, the new TC limits
(%/oC) can be estimated using the graph in FIGURE 1.
At a test current of 6.0mA the change in Temperature Coefficient
(TC) is approximately –0.0009%.oC. The algebraic sum of +/-
0.005%oC and –0.0009%/oC gives the new estimated limits of
+0.0041%/oC and -0.0059%/oC.
