JSM546 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 | VCC | power_in | Supply voltage pin with a recommended range of 3.0 V to 30 V, an absolute maximum of 20 V for t < 1000 h, and reverse-voltage protection. |
| 2 | GND | power_in | Ground reference; all voltages in the datasheet are referenced to this pin. |
| 3 | Vout | output | Open-drain output (current source in 2-wire devices) with a recommended maximum output voltage of 30 V and output current of 25 mA. |
