DT-670-SD features Best accuracy across the widest useful temperature range—1.4 K to 500 K—of any silicon diode in the industry Tightest tolerances for applications from 30 K to 500 K of any silicon diode to date Rugged, reliable Lake Shore SD package designed to withstand repeated thermal cycling and minimize sensor self-heating Conformance to standard Curve DT-670 temperature response curve Variety of packaging options DT-670E-BR features Temperature range: 1.4 K to 500 K Bare die sensors with the smallest size and fastest thermal response time of any silicon diode on the market today Non-magnetic sensor DT-621-HR features Temperature range: 1.4 K to 325 K* Non-magnetic package Exposed flat substrate for surface mounting *Calibrated down to 1.4 K, uncalibrated (Curve DT-670) to 20 K DT-670 Silicon Diodes DT-670 Series silicon diodes offer better accuracy over a wider temperature range than any previously marketed silicon diodes. Conforming to the Curve DT-670 standard voltage versus temperature response curve, sensors within the DT-670 series are interchangeable, and for many applications do not require individual calibration. DT-670 sensors in the SD package are available in four tolerance bands – three for general cryogenic use across the 1.4 K to 500 K temperature range, and one that offers superior accuracy for applications from 30 K to room temperature. DT-670 sensors also come in a seventh tolerance band, B and E, which are available only as bare die. For applications requiring greater accuracy, DT-670-SD diodes are available with calibration across the full 1.4 K to 500 K temperature range.
