Not internally bonded; leave floating or tie to ground for mechanical support. |+| 2 | NC | unconnected | No connect. Not internally bonded; leave floating or tie to ground for mechanical support. |+| 3 | VDD | power_in | Supply voltage input, 1.8 V to 5.5 V. Powers the temperature sensor, ADC and digital core; typical standby current 0.2 μA at 5 V, average 5 μA at 1 Hz sampling. |+| 4 | DQ | bidirectional | 1-Wire bidirectional data pin. Open-drain data I/O for the single-wire bus protocol; requires an external pull-up resistor to VDD (typ. 4.7 kΩ, or 1 kΩ for long-line / multi-drop networks). Carries all ROM commands, function commands, temperature data and alarm search responses. |+| 5 | GND | power_in | Ground reference for the supply and 1-Wire signal. |+| 6 | NC | unconnected | No connect. Not internally bonded; leave floating or tie to ground for mechanical support. |+| 7 | NC | unconnected | No connect. Not internally bonded; leave floating or tie to ground for mechanical support. |+| 8 | NC | unconnected | No connect. Not internally bonded; leave floating or tie to ground for mechanical support. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Mysentech |+| Package | SOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `MY18B20Z`+- `MY18B20Z-15`+- `MY18B20ZD10`+- `MY18B20ZMY18E20`+- `MY18B20ZMY18E20-15`+- `MY18B20ZMY18E20D10`+- `MY18B20ZMY1820`+- `MY18B20ZMY1820-15`+- `MY18B20ZMY1820D10`+- `MY18B20ZMY18B20L`+- `MY18B20ZMY18B20L-15`+- `MY18B20ZMY18B20LD10`++## CAD (KiCad official)++- Symbol: `MY18B20Z`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Mysentech datasheet](docs/my18b20z-datasheet.pdf) (28 pp, sha256 `47a9f5f3f1da5bbc`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
