Gauge pressure sensor die C32/2
Cautions and warnings
Storage (general)
All pressure sensors should be stored in their original packaging. They should not be placed in harmful environments such as
corrosive gases, or be exposed to heat or direct sunlight, which may cause deformations. Similar effects may result from
extreme storage temperatures and climatic conditions. Avoid storing the sensor dies in an environment where condensation
may form, or in a location exposed to corrosive gases, which will adversely affect their performance. Plastic materials should
not be used for wrapping/packing when storing or transporting these dies, as they may become charged. Pressure sensor
dies should be used soon after opening their seal and packaging.
Storage conditions
Used materials for storage should be ESD protective according JESD625, non-outgassing, and chemically stable.
Furthermore the following storage conditions should be preserved:
1. Storage in cabinets (if shipment package is opened):
a. Atmosphere: inert gas, dry air or dry nitrogen
b. Temperature range (in cabinet): 20±3 °C
c. Relative humidity range (in cabinet): < 40 %
d. Particle count (in cabinet): Class 6 per ISO 14644:1999 (equivalent FED STD 209E Class 1000)
e. Shelf life under these conditions: 24 months for deliveries in trays
f. Shelf life under these conditions: 12 months for deliveries on tape
2. Storage in containers (if shipment package is sealed):
a. Sealed as delivered or backfilled with inert gas, dry air or dry nitrogen and re-sealed
b. Temperature range: 20±3 °C
c. Relative humidity range: < 50 %
d. Particle count (during backfill): Class 6 per ISO 14644:1999 (equivalent FED STD 209E Class 1000)
e. Shelf life under these conditions: 12 months for deliveries in trays
f. Shelf life under these conditions: 6 months for deliveries on tape
After delivery, the product can be stored under specific conditions for the specified shelf life.

Operation (general)
Media compatibility with the pressure sensors must be ensured to prevent their failure. The use of other media can cause
damage and malfunction. Never use pressure sensors in atmospheres containing explosive liquids or gases.
Ensure pressure equalization to the environment, if gauge pressure sensors are used. Avoid operating the pressure sensors
in an environment where condensation may form, or in a location exposed to corrosive gases. These environments adversely
affect their performance.
If the operating pressure is above the rated overpressure range, it may change the output characteristics. This may also
happen with pressure sensor dies if an incorrect mounting method is used. Be sure that the applicable pressure does not
exceed the overpressure, as it may damage the pressure sensor.
Do not exceed the maximum rated supply voltage nor the rated storage temperature range, as it may damage the pressure
sensor.
Temperature variations in both the ambient conditions and the media (liquid or gas) can affect the accuracy of the output signal
from the pressure sensors. Be sure to check the operating temperature range and thermal error specification of the pressure
sensors to determine their suitability for the application.
Connections must be wired in accordance with the terminal assignment specified in the data sheets. Care should be taken as
reversed pin connections can damage the pressure transmitters or degrade their performance. Contact between the pressure
sensor terminals and metals or other materials may cause errors in the output characteristics.
Design notes (dies)
This specification describes the mechanical, electrical and physical requirements of a piezoresistive sensor die for measuring
pressure. The specified parameters are valid for the pressure sensor die with pressure application either to the front or back
side of the diaphragm as described in the data sheet. Pressure application to the other side may result in differing data. Most
of the parameters are influenced by assembly conditions. Hence, these parameters and the reliability have to be specified for
each specific application and tested over its temperature range by the customer.
