SPICE model
Hewlett-Packard is tracking the mean and standard deviation for five key SPICE parameters for this diode. They are n (ideality factor),
IS (saturation current), RS (series resistance), CJO (junction capacitance at zero reverse voltage and 1 MHz) and BV (breakdown voltage).
Measurements are made on 20 samples, randomly selected, from each lot manufactured and the mean and standard deviation data are
obtained and stored. The data shown below are the mean of the mean values of all lots manufactured since November, 1996 and the
standard deviation is that for the mean values of all such lots.
The parameters are for a single diode (HSMS-2820). Parameters also apply to the individual diodes within multiple diode configurations.

In certain applications, the degree of match between two or four diodes in the same package is of importance. The automatic equipment used at HP to assemble
Schottky dice into plastic packages selects chips from adjacent sites on the wafer, thus insuring the highest degree of match. Twenty HSMS-2825 diode pairs
from one lot were measured and their five key SPICE parameters extracted. Listed below are the mean value for all 40 diodes, the mean
 or difference between the two diodes in a package and this difference expressed as a percent of the mean value.
Note that the mean values listed below are slightly different from those given in the table above since they represent a single lot of diodes. The majority of
for CJO is due to the inability to measure capacitance in picofarads to three decimal places.

| CJO | pF | 0.74 | 0.018 | 1.2% |
| IS | A | 2.42E-8 | 1.79E-9 | 3.7% |
