MCP606T-I from Microchip, in a SOT-23-5. 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 internal connection to the IC. Leave floating or tie to any convenient net; making no connection is recommended.
2	-IN	input	Inverting input terminal of the op amp. High-impedance CMOS input (10^13 Ohm
3	+IN	input	Non-inverting input terminal of the op amp. High-impedance CMOS input (10^13 Ohm
4	VSS	power_in	Negative power supply pin (analog ground in single-supply applications). Absolute range: 0 V to -7 V relative to Vdd. Typically tied to GND for single-supply operation.
5	NC	unconnected	No internal connection to the IC. Leave floating or tie to any convenient net.
6	OUT	output	Op-amp output. Rail-to-rail swing to within ~15-60 mV of the supply rails at RL=25 kOhm. Short-circuit output current 17 mA typ. Absolute max continuous current +/-30 mA.
7	VDD	power_in	Positive power supply pin. Operating range 2.5 V to 5.5 V (absolute max 7.0 V). Iq = 18.7 uA typ, 25 uA max per amplifier at Io = 0. Bypass with a local 0.1 uF ceramic capacitor to Vss.
8	NC	unconnected	No internal connection to the IC. Leave floating or tie to any convenient net.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mcp606t-i.step`	85 KB	You want the bare part, or you mark your own boards.
`mcp606t-i-etched.step`	1.7 MB	You want the part with `MCP606T-I` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 406 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.
