Description

TMP61/TMP61-Q1 Silicon Linear Thermistors have a linear positive temperature coefficient (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 TMP61/TMP61-Q1 offers enhanced linearity and consistent sensitivity across the full temperature range. They also have robust performance due to their immunity to environmental variation and their built-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-sized transistor-outline TO-92S package. The TMP61-Q1 devices are AEC-Q100 qualified for automotive applications.
