SM5420-100-A-H-S

SILICON MICROSTRUCTURES INCORPORATED • • SM5420 Low-Cost, SO-8 Packaged Pressure Sensor For High-Volume Applications Ultra-Small, Low Cost OEM Pressure Package DESCRIPTION The SM5420 is a small outline SO-8 packaged pressure sensor. The sensor uses SMI’s SM5108 micromachined, piezoresistive pressure sensing chip that has been optimized to provide the highest possible accuracy for a package of this size. This performance is achieved through careful resistor placement and mechanical configuration along with advanced MEMS processing. This sensor is intended for high volume applications where cost is a critical factor, such as consumer tire pressure gauges or automotive tire pressure monitoring. The SM5420 is available as an absolute pressure sensor in full-scale ranges of 15 PSI, 30 PSI, 60 PSI, and 100 PSI. It is designed to be surface-mounted on ceramic or PC board substrates by high-volume OEM manufacturers. The SM5420 is available in a ported configuration to allow positive positioning of a pressure source over the inlet or in a nonported configuration to be used for sensing general environmental pressures or with an oring seal. The port position has been chosen to minimize the chance of pressure pulses directly impacting the face of the sensor die for added long-term reliability in hostile environments. The part comes with gel over the die as standard; the part can be ordered without gel in high volumes where the maximum stability is required, such as in barometric, weather station sensing applications. Please contact SMI for more information. The SM5420 is shipped either in IC tubes or in tape-and-reel. Custom pressure ranges are available in highvolume applications. Minimum order quantities apply to this product.
