SC2242UA-BK-Q from Semiment SC2242UA, in a TO-92S. 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 | VDD | power_in | 2.5 V to 24 V supply input. Absolute maximum ±28 V; reverse-supply protected to -28 V. Recommend a 0.1 µF bypass (C1) close to the pin, and an optional 100 Ω series resistor (R1) for unregulated supplies. |
| 2 | GND | power_in | Ground reference for the device. (TO-92S 'UA' package: pin 2 is GND; SOT-23-3L 'SO' package places GND on pin 3.) |
| 3 | OUT | output | Open-drain latched Hall output with an internal 10 kΩ pull-up to VDD. Drives LOW (turn-on) when the south-pole B-field exceeds B_OP (typ. +2.0 mT); releases HIGH when B falls below B_RP (typ. -2.0 mT). Sinks up to 20 mA; V_OUT absolute max 28 V with a 1 kΩ pull-up. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 507 faces against 19 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.
