TPNLASB3157DFT2G from TECH PUBLIC, in a SOT-363. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B1 | bidirectional | Independent switch throw terminal 1. Bidirectional analog signal path, connected to A when S (select) = HIGH. Rated -0.3V to +5.5V input signal range with typical Ron = 6Ω at VCC=5V. |
| 2 | GND | power_in | Ground reference (0 V) for the device. |
| 3 | B0 | bidirectional | Independent switch throw terminal 0. Bidirectional analog signal path, connected to A when S (select) = LOW. Rated -0.3V to +5.5V input signal range with typical Ron = 6Ω at VCC=5V. |
| 4 | A | bidirectional | Common pole terminal of the SPDT switch. Routed to either B0 or B1 depending on the state of the S (select) control input. Continuous current rating ±128 mA. |
| 5 | VCC | power_in | Positive supply voltage input. Operating range 1.65V to 5.5V (absolute max +6.5V). Typical quiescent current <2 µA. |
| 6 | S | input | Digital select input. LOW connects B0→A; HIGH connects B1→A. 1.8V logic compatible: VIH ≥ 1.6V (VCC=3.3-5.5V) or ≥1.4V (VCC=1.5-3.3V); VIL ≤ 0.6V / 0.4V respectively. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|

99 KB | You want the bare part, or you mark your own boards. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 654 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
