AnBon · ESD And Surge Protection (TVS/ESD) · SOD-123
SMF40CA from AnBon, 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 | A1 | passive | Bi-directional TVS terminal on the left end of the SOD-123 outline (no cathode band on the C-suffix part); the datasheet gives no pin label for the bi-directional device, so this is the left-hand terminal and is interchangeable with pin 2. |
| 2 | A2 | passive | Bi-directional TVS terminal on the right end of the SOD-123 outline (no cathode band on the C-suffix part); the datasheet gives no pin label for the bi-directional device, so this is the right-hand terminal and is interchangeable with pin 1. |
