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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Semiment SC2242UA |+| Package | TO-92S |+| Category | Sensor |+| Pins | 3 |++## Ordering variants++- `SC2242UA-BK-QUA-BK`+- `SC2242UA-BK-QUA-BK-Q`+- `SC2242UA-BK-QSO-TR-Q`++## CAD (KiCad official)++- Symbol: `SC2242UA-BK-Q`+- Footprint: `Package_TO_SOT_THT:TO-92_Inline`+- 3D model: TO-92S (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Semiment SC2242UA datasheet](docs/sc2242ua-bk-q-datasheet.pdf) (13 pp, sha256 `abcd2fb8d6021ef5`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
