Cryogenic Temperature Sensors

The CY670 Series silicon diodes offer an accurate reading of temperature ranges. Conforming to the curve CY670 standard voltage versus temperature response curve, sensors within the CY670 Series are interchangeable, and for many applications they do not require calibration. CY670 Series sensors in the SD package are available in five tolerance bands – three for cryogenic use across the 1.4 to 500 K temperature range, and one that offers superior accuracy for applications from 30 K to room temperature. The CY670 Series sensors also come in a tolerance band (E), which is available only as a bare die.
