SEMF12

SINO-IC · TVS · SOT-353

SEMF12 from SINO-IC, in a SOT-353. 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/O1 passive TVS protected line channel 1 (steering diodes to pin 2 and pin 5 node), part of up to four bidirectional lines, VRWM 12 V for SEMF12.
2 GND power_in Common ground/reference node of the TVS array, connected to the central diode junction.
3 I/O2 passive TVS protected line channel 2 (steering diodes to the common node), VRWM 12 V for SEMF12.
4 I/O3 passive TVS protected line channel 3 (steering diodes to the common node), VRWM 12 V for SEMF12.
5 I/O4 passive TVS protected line channel 4 (steering diodes to the common node), VRWM 12 V for SEMF12.
