6 Environmental Stability
The SHT2x sensor series were tested based on AEC-
Q100 Rev. G qualification test method where applicable.
Sensor specifications are tested to prevail under the AEC-
Q100 temperature grade 1 test conditions listed in Table
912. Sensor performance under other test conditions
cannot be guaranteed and is not part of the sensor
specifications. Especially, no guarantee can be given for
sensor performance in the field or for customer’s specific
application.

4.1.
If sensors are qualified for reliability and behavior in
extreme conditions, please make sure that they
experience same conditions as the reference sensor. It
should be taken into account that response times in
assemblies may be longer, hence enough dwell time for
the measurement shall be granted. For detailed
information please consult Application Note “Qualification
Guide”.
7 Packaging
7.1
Packaging Type
SHT2x sensors are provided in DFN packaging (in
analogy with QFN packaging). DFN stands for Dual Flat
No leads.
The sensor chip is mounted to a lead frame made of Cu
and plated with Ni/Pd/Au. Chip and lead frame are over
molded by green epoxy-based mold compound. Please
note that side walls of sensors are diced and hence lead
12 Sensor operation temperature range is -40 to 125°C (AEC-Q100 temperature
grade 1).
13 According to accuracy and long term drift specification given on Page 2.
frame at diced edge is not covered with respective
protective coating. The total weight of the sensor is 25mg.
7.2
Filter Cap and Sockets
For SHT2x a filter cap SF2 is available. It is designed for
fast response times and compact size. Please find the
datasheet on Sensirion’s web page.
For testing of SHT2x sensors sockets, such as from
Plastronics,
part
number
10LQ50S13030
are
recommended (see e.g. www.locknest.com).
7.3
Traceability Information
All SHT20 are laser marked with an alphanumeric, five-
digit code on the sensor – see Figure 11.
Figure 11 Laser marking on sensor. For details see text.
The marking on the sensor consists of two lines with five
digits each. The first line denotes the sensor type
(SHT20). The first digit of the second line defines the
output mode (D = digital, Sensibus and I2C, P = PWM, S =
SDM). The second digit defines the manufacturing year (0
= 2010, 1 = 2011, etc.). The last three digits eventually
represent an alphanumeric tracking code. That code can
be decoded by Sensirion only and allows for tracking on
batch level through production, calibration and testing –
and will be provided upon justified request.
Reels are also labeled, as displayed in Figure 12 and
Figure 13, and give additional traceability information.
Figure 12: First label on reel: XX = Sensor Type (20 for SHT20),
O = Output mode (D = Digital, P = PWM, S = SDM), NN =
product revision no., Y = last digit of year, RRR = number of
sensors on reel divided by 10 (200 for 2000 units), TTTTT =
Traceability Code.
