The TMP61xx series of Silicon Linear Thermistors has a linear positive temperaturecoefficient (PTC) that results in a uniform, consistent temperature coefficient resistance (TCR)across a wide operating temperature range. These devices are designed for temperature measurement,protection, compensation, and control systems. Compared to traditional NTC thermistors, the TMP61xxseries of devices offers enhanced linearity and consistent sensitivity across the full temperaturerange. They also have robust performance due to their immunity to environmental variation and theirbuilt-in fail-safe behavior at high temperatures. These devices are currently available in a 2-pin,surface-mount, 0402 footprint-compatible X1SON package and a 2-pin, through-hole, mini-sizedtransistor-outline TO-92S package.
