TPSMF4L6.0A from Littelfuse, in a SOD-123FL. 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 | Cathode | passive | Cathode of the uni-directional TVS diode, marked by the color band/cathode brand; connect to the protected line, with VR 6.0V stand-off and VBR 6.67-7.37V at 10mA. |
| 2 | Anode | passive | Anode of the uni-directional TVS diode, connected to ground/return; clamps to 10.3V max at Ipp 35.9A (10/1000µs). |
