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. |
