TPSMF4L5.0A 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/cathode band, connected to the protected line (reverse stand-off voltage VR 5.0 V for the TPSMF4L5.0A). |
| 2 | Anode | passive | Anode of the uni-directional TVS diode, normally connected to ground/return, with the device clamping at a maximum of 9.2 V at Ipp 40.1 A. |
