RH6015D from RONGHE Microelectronics, 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	OD	output	NMOS open-drain output. Pulls low when touch is detected (active-low, fixed); high-impedance when idle. Sink capability I_OL = 30 mA at V_OL = 0.3*VDD. Requires an external pull-up to VDD.
2	GND	power_in	Ground / negative supply reference (VSS). Bypass with local decoupling to VDD as close to the IC as possible.
3	TCH	bidirectional	Capacitive touch sense input/output. Connects to the touch electrode through a series resistor Rs (~1 kohm recommended) with an optional sensitivity-tuning capacitor Cj (1-50 pF) to GND. Sensitivity decreases as Cj increases.
4	NC	unconnected	No connect on the RH6015-D variant. (On RH6015-C this pin is the AHLB polarity-select input; RH6015-D output polarity is fixed active-low, so the pin is unused.)
5	VDD	power_in	Positive supply, 2.3-5.5 V (typ 3.0 V). Internal high-precision LDO regulates the analog front-end. Add local 10 uF + 0.1 uF decoupling to GND close to the pin; external LDO recommended if supply ripple exceeds the internal LDO's rejection.
6	TOG	input	Sync / hold mode select input with internal pull-down (I-PL). TOG = 0 (default, floating) selects synchronous mode (output follows touch state); TOG = 1 (tied to VDD) selects hold/toggle mode (output latches on each touch).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`rh6015d.step`	97 KB	You want the bare part, or you mark your own boards.
`rh6015d-etched.step`	1.6 MB	You want the part with `RH6015D` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 387 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.
