SMI Pressure Sensors (Si Micro)

SM6841 ABSOLUTE PRESSURE SENSOR

The SM6841 is a small outline S0-8 packaged pressure sensor that incorporates SMl's SM5108C MEMS piezoresistive pressure sensing die. The SM6841 has been optimized to provide the highest possible accuracy for a package of this size. Performance is achieved through careful resistor placement and mechanical configuration along with advanced MEMS processing.

The packaged sensor is intended for high volume applications where cost is a critical factor,such as consumer and automotive products. The SM6841 is available as an absolute pressure sensor in full-scale range of 30 & 100 PSI (200 & 700 kPa). It is designed to be surface-mounted on ceramic or PC board substrates by high-volume OEM manufacturers.

The SM6841 is available in a non-ported, centered hole, configuration that is designed to be immersed in the media being measured.

The standard configuration offers a protective gel over the die. A non-gel version is also available for high volumes where the maximum stability is required, such as in barometric, weather station sensing applications. The SM6841 is shipped tape & reel.
