SMF43CA 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 | Bidirectional TVS terminal 1 (no polarity); the SMF43CA has no cathode band, 43 V reverse standoff, 47.8-52.8 V breakdown at 1.0 mA, 69.4 V max clamping at 2.9 A. |
| 2 | A2 | passive | Bidirectional TVS terminal 2 (no polarity); the SMF43CA conducts and clamps in either direction, 200 W peak pulse power (10x1000us). |
