TS5A63157DCKR from Texas Instruments, in a SC-70-6. 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	NO	passive	Normally-open analog switch terminal. Connected to COM when IN is logic high. Analog voltage range 0 V to V+, on-state current up to ±50 mA, r_on ≈ 12 Ω typical.
2	GND	power_in	Digital ground reference for the device. Continuous current through GND is limited to ±100 mA.
3	NC	passive	Normally-closed analog switch terminal. Connected to COM when IN is logic low. Analog voltage range 0 V to V+, on-state current up to ±50 mA, r_on ≈ 12 Ω typical.
4	COM	passive	Common analog switch terminal (pole). Connects to either NO or NC based on the IN control input. Analog voltage range 0 V to V+.
5	V+	power_in	Positive supply input. Recommended operating range 1.65 V to 5.5 V (absolute max 6.5 V). Continuous current through V+ limited to ±100 mA.
6	IN	input	Digital control input, 5-V tolerant. Logic H connects COM to NO; logic L connects COM to NC. VIH ≥ 0.7×V+, VIL ≤ 0.3×V+.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ts5a63157dckr.step`	99 KB	You want the bare part, or you mark your own boards.
`ts5a63157dckr-etched.step`	2.5 MB	You want the part with `TS5A63157DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 608 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.
