PSM712L from TECH PUBLIC, 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 | I/O 1 | passive | I/O 1 protected line; the 12V TVS runs from pin 1 to pin 3 (VRWM 12V max, VBR 13.3V min at 1mA) and the 7V TVS from pin 3 to pin 1 (VRWM 7V max, VBR 7.5V min at 1mA). |
| 2 | I/O 2 | passive | I/O 2 protected line; the 12V TVS runs from pin 2 to pin 3 (VRWM 12V max, VBR 13.3V min at 1mA) and the 7V TVS from pin 3 to pin 2 (VRWM 7V max, VBR 7.5V min at 1mA). |
| 3 | GND | power_in | Common ground connection shared by both TVS channels, tied to the junction of the 7V diodes. |
