INA213AIDCKR 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	REF	input	Reference voltage input. Sets the output voltage bias so bidirectional (positive/negative) shunt currents can be represented on the single-supply output. Valid range 0 V to V+.
2	GND	power_in	Device ground reference (0 V).
3	V+	power_in	Positive power supply, 2.7 V to 26 V. Quiescent current is 100 uA (maximum). Decouple with 0.01 uF to 0.1 uF bypass capacitor to GND.
4	IN+	input	Non-inverting analog input. Connects to the supply (high-potential) side of the external current-sense shunt resistor. Common-mode range -0.3 V to 26 V, independent of V+.
5	IN-	input	Inverting analog input. Connects to the load (low-potential) side of the external current-sense shunt resistor. Common-mode range -0.3 V to 26 V, independent of V+.
6	OUT	output	Analog output voltage. VOUT = (ILOAD x RSHUNT) x Gain + VREF, where Gain = 50 V/V for INA213. Rail-to-rail output swings from (VGND + 5 mV) up to (V+) - 0.05 V with a 10 kOhm load.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ina213aidckr.step`	99 KB	You want the bare part, or you mark your own boards.
`ina213aidckr-etched.step`	2.0 MB	You want the part with `INA213AIDCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 513 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.
