Frequently Asked Questions
What resistance value and tolerance does TMP6331QDYATQ1 provide at 25°C?
TMP6331QDYATQ1 has a nominal resistance of 100 kΩ at 25°C with a tight 1% tolerance, ensuring consistent temperature measurements across production lots without individual calibration. This precision reduces system-level error budgets in automotive temperature sensing circuits operating from 3.3 V or 5 V supply rails.
Which automotive thermal protection circuits benefit from the linear NTC characteristic of TMP6331QDYATQ1?
Battery management systems, electric motor drives, and HVAC controllers benefit most, because the linear resistance-vs-temperature curve across -40°C to +150°C maps directly to ADC counts without a software linearization table. A simple voltage divider with a 100 kΩ reference resistor yields output voltage that is nearly proportional to temperature over that full 190°C span.
How does the SOT-5X3 footprint of TMP6331QDYATQ1 compare to a standard SOT-23 for board-space-constrained designs?
The SOT-5X3 body measures only 1.3 mm × 0.85 mm with a 0.7 mm profile, which is approximately 30% smaller in area than a standard SOT-23 package (2.9 mm × 1.3 mm). This reduction allows designers to place the thermistor closer to the heat-generating component on a dense automotive ECU PCB, improving thermal coupling and measurement accuracy.
Is TMP6331QDYATQ1 qualified for automotive use, and what packaging is available for production assembly?
Yes, TMP6331QDYATQ1 carries AEC-Q200 automotive qualification, confirming reliability through stress tests covering the -40°C to +150°C automotive temperature range. It is supplied in 7-inch tape-and-reel (TR) format, compatible with standard pick-and-place equipment, and the JESD-609 code e3 indicates a RoHS-compliant, lead-free finish suitable for automotive production lines.
