Littelfuse · TVS · SOD-123FL
TPSMF4L64A 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 unidirectional TVS diode, marked by the color band/cathode brand on the package; connect to the protected line (positive side), with VR 64 V stand-off and VBR 71.1-78.6 V at 1 mA. |
| 2 | Anode | passive | Anode of the unidirectional TVS diode, normally connected to ground/return, with maximum clamping voltage 103.0 V at Ipp 3.9 A. |
