JSM422 from JSMSEMI, in a SOT-23. 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; the datasheet specifies an operating supply range of 3.8 V to 40 V (VSUP typical test condition 5 V), with reverse-voltage protection on the supply. |
| 2 | GND | power_in | Ground pin for the device. |
| 3 | VOUT | output | Open-collector output that requires an external pull-up resistor; absolute maximum output voltage is 60 V and maximum sink current is 40 mA. |
