TMP6431QDECRQ1 Description

Short technical summary and product information.

The Texas Instruments TMP6431QDECRQ1 is a silicon-based, positive temperature coefficient (PTC) linear thermistor designed for automotive applications. It features a nominal resistance of 47 kΩ at 25°C with a tight tolerance of ±1% across the 0°C to 70°C range. The device offers consistent sensitivity across its operating temperature range, with a typical TCR of 6400 ppm/°C at 25°C and a TCR tolerance of 0.2%.

 

This thermistor has a fast thermal response time of 0.6 seconds and is built for long lifetime and robust performance, including a fail-safe mechanism for short-circuit failures. It is qualified to AEC-Q100 Grade 1 standards, operating from -40°C to 125°C. An alternative AEC-Q100 Grade 0 (DYA) option extends the operating temperature to 150°C.

 

The TMP6431QDECRQ1 is available in a 0402 footprint-compatible package, specifically the X1SON package, suitable for surface mounting. Its linear resistance change and consistent sensitivity simplify temperature conversion methods, making it ideal for thermal compensation and threshold detection in various automotive systems.
