TPG4599S6 from TECH PUBLIC, in a SOT-23-6. 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	SELECT	input	Digital channel-select control input. 1.8V logic compatible: L selects NC channel (COM↔NC), H selects NO channel (COM↔NO). VIH ≥ 1.6V (VCC=3.3-5.5V) or ≥ 1.4V (VCC=1.5-3.3V); VIL ≤ 0.6V / 0.4V respectively. Absolute max VSEL = -0.3 to +5.5V.
2	V+	power_in	Positive supply voltage input (VCC). Operating range 1.5V to 5.5V; absolute max -0.3 to +6.5V. Typical quiescent current ICC < 1µA.
3	GND	power_in	Ground reference (0V) for the device.
4	NC	bidirectional	Normally-Closed switch terminal. Independent input or output of the SPDT analog switch; connected to COM when SELECT = L. Ron ≈ 1.7Ω at VA=5V; bidirectional analog signal path (-0.3 to +5.5V, ±128 mA continuous).
5	COM	bidirectional	Common pole of the SPDT switch. Routed to either NC or NO depending on SELECT state. Bidirectional analog signal path with -3dB bandwidth of 700MHz.
6	NO	bidirectional	Normally-Open switch terminal. Independent input or output of the SPDT analog switch; connected to COM when SELECT = H. Ron ≈ 1.7Ω at VA=5V; bidirectional analog signal path (-0.3 to +5.5V, ±128 mA continuous).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tpg4599s6.step`	97 KB	You want the bare part, or you mark your own boards.
`tpg4599s6-etched.step`	2.1 MB	You want the part with `TPG4599S6` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 495 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.
