SM5108-030-A

SILICON MICROSTRUCTURES INCORPORATED • • SM5108 Ultra-Small, Low-Cost, OEM Pressure Die For Extremely High-Volume Applications Ultra-Small, Low Cost OEM Pressure Die DESCRIPTION The SM5108 is a extremely small (0.65 mm x 0.65 mm) silicon micromachined piezoresistive pressure sensing chip that has been optimized to provide the highest possible accuracy for a die of this size. This performance is achieved through careful resistor placement and mechanical configuration. The small die results in a significant cost saving when compared to larger sensor die. Over 24,000 die come on a 150 mm wafer. This sensor is intended for high volume applications where cost is a critical factor, such as consumer tire pressure gauges or disposable pressure gauges. The SM5108 is available as an absolute pressure sensor in full-scale ranges of 15 PSI, 30 PSI, 60 PSI, and 150 PSI. It is designed to be mounted on ceramic or PC board substrates by highvolume OEM manufacturers. Die are probed, diced, and visually inspected and shipped on tape in rings. Custom pressure ranges are available in high-volume applications. Minimum order quantities apply to this product.
