JSM8233 from JSMSEMI, in a SOT-23-6L. 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	OUT	output	CMOS push-pull output. Drives high or low on touch response depending on OLH configuration. IOL = 2 mA min / 4 mA typ at VOL = 0.7 V.
2	GND	power_in	Negative supply / ground reference. All voltages are referenced to GND.
3	TCH	input	Touch pad sense input. Connects to the external TOUCH PAD electrode; an optional 0-75 pF tuning capacitor Cj to GND adjusts sensitivity.
4	OLH	input	Output-active-level select. OLH=0 (default, internal pull-down) => OUT goes HIGH on touch response; OLH=1 => OUT goes LOW on touch response. Internal pull resistor ~50-200 kΩ.
5	VDD	power_in	Positive supply, 2.0-5.5 V (typ 3.0 V). Decouple with >=10 uF to GND for stable sensitivity.
6	HLD	input	Hold/Sync mode select. HLD=0 (default, internal pull-down) => Sync mode: OUT tracks touch. HLD=1 => Hold/Toggle mode: OUT toggles state on each touch. Internal pull ~50-200 kΩ.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`jsm8233.step`	97 KB	You want the bare part, or you mark your own boards.
`jsm8233-etched.step`	1.9 MB	You want the part with `JSM8233` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 451 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.
