SMF64A
Shandong Jingdao Microelectronics · TVS · SOD-123FL
SMF64A from Shandong Jingdao Microelectronics, 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 terminal of the unidirectional SMF64A TVS diode, which is the pin marked as the cathode in the pinning table; the datasheet gives no separate electrical limit for this pin. |
| 2 | Anode | passive | Anode terminal of the unidirectional SMF64A TVS diode, which is the pin marked as the anode in the pinning table; the datasheet gives no separate electrical limit for this pin. |
