JSM3144UA from JSMSEMI, in a TO-92S. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VSUP | power_in | Supply pin for the Hall switch, operating from 3.8 V to 40 V, with absolute maximum supply voltage VDD of -60 V to 60 V. |
| 2 | GND | power_in | Ground pin for the device. |
| 3 | VOUT | output | Open-collector output that requires an external pull-up resistor, with absolute maximum output voltage of -0.5 V to 60 V and maximum sink current of 40 mA. |
