PSM712-LF-T7-L

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-23

PSM712-LF-T7-L 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 Asymmetrical TVS I/O 1 protected line; 12V TVS (VRWM 12V max, VBR 13.3V min at 1mA) from pin 1 to pin 3 and 7V TVS (VRWM 7V max, VBR 7.5V min) from pin 3 to pin 1.
2 I/O 2 passive Asymmetrical TVS I/O 2 protected line; 12V TVS (VRWM 12V max, VBR 13.3V min at 1mA) from pin 2 to pin 3 and 7V TVS (VRWM 7V max, VBR 7.5V min) from pin 3 to pin 2.
3 GND power_in Common ground connection shared by both TVS channels, to which I/O 1 and I/O 2 are clamped.
