TMP6331DYAR

Texas Instruments · Others · SOD-523

TMP6331DYAR from Texas Instruments, in a SOD-523. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 , passive Thermistor negative (-) terminal; the + terminal must be at a higher voltage potential than this pin, with a maximum of 6 V across pins 2 and 1 (absolute maximum) and 5.5 V recommended.
2 + passive Thermistor positive (+) terminal; must be biased at a higher voltage than the - terminal for proper operation, with a recommended maximum of 5.5 V across pins 2 and 1 and a maximum current of 40 µA.
