COS1416 from COSINE, in a SOT23-5. 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	NC	unconnected	No connection. Leave floating or tie to GND for mechanical stability.
2	VDD	power_in	Bias supply input for the MOSFET driver, rated 4.5V to 25V with respect to GND. Bypass with a local ceramic capacitor (1.0 uF suggested) sized to the capacitive load.
3	IN	input	High-impedance TTL/CMOS compatible control input with 300 mV of hysteresis (VIH = 1.8V min, VIL = 0.7V max). Withstands negative inputs down to GND-5V.
4	GND	power_in	Device ground return. Requires a low-impedance connection to the bias supply return since high peak discharge currents flow through this pin.
5	OUT	output	Low-impedance CMOS push-pull driver output. Non-inverting with respect to IN on COS1416; delivers 1.5A peak source/sink into 1000pF, 200 mA continuous, with ~2 ohm pull-up/pull-down.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cos1416.step`	85 KB	You want the bare part, or you mark your own boards.
`cos1416-etched.step`	1.4 MB	You want the part with `COS1416` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 353 faces against 102 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.
