V.F. Mitin, V.V. Kholevchuk
Applications:
Diode temperature sensor can be used for static and dynamic temperature measurements in the 1.5 K to 450 K temperature range.
Description:
The temperature sensing element for thermometer is a silicon p+-n-n+ planar diode. The size of the diode structure is 0.35 mm x 0.35 mm x 0.2 mm. This sensitive element is placed in various nonmagnetic packages. At present three types of sensor packages are offered: cylindrical canister package, made of gold plated copper (3 mm in diameter and 5.0 mm long), micro-package (1.2 mm in diameter and 1.0 mm long) and micro-package on plate (2 mm square by 0.15 mm thick).
Main advantages:
• small size
• extremely fast response to temperature changes
• high quality and low price
Operating characteristics:
Voltage, U, and sensitivity, dU/dT, vs. temperature curves at different currents
