# NST1001-QTZB

**NOVOSENSE** · Temperature Sensors · TO-92S

NST1001-QTZB from NOVOSENSE, in a TO-92S. 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 | DQ | bidirectional | Supply and digital I/O pin that powers the device from a 1.65V to 5.5V MCU GPIO and returns the temperature as a pulse-count output on the same line, with an external pull-up resistor. |
| 2 | GND | power_in | Ground. |
| 3 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `NST1001-QTZB`
- Footprint: `Package_TO_SOT_THT:TO-92_Inline`
- 3D model: TO-92S (KiCad packages3D, STEP)
- 3D model files: `nst1001-qtzb-etched.step` / `nst1001-qtzb-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `nst1001-qtzb.step` / `nst1001-qtzb.glb` are the bare package body.
