FUXINSEMI · ESD And Surge Protection (TVS/ESD) · SOD-123
SMF4L36A from FUXINSEMI, in a SOD-123. 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 | K | passive | Cathode terminal, marked by the cathode band on the package; for the unidirectional SMF4L36A it connects to the protected line, with a 36.0 V working peak reverse voltage and 40.00-44.20 V breakdown at 1 mA. |
| 2 | A | passive | Anode terminal, the end opposite the cathode band; for the unidirectional SMF4L36A it connects to ground, with a 58.1 V maximum clamping voltage at 6.88 A peak pulse current. |
