SMF54CA 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 | 1 | passive | Bi-directional TVS terminal (SMF54CA, 54 V standoff, 60.0-66.3 V breakdown at 1.0 mA); the datasheet numbers this as the cathode-band end only for uni-directional parts, and no polarity band is marked on bi-directional parts. |
| 2 | 2 | passive | Bi-directional TVS terminal (SMF54CA, 54 V standoff, 87.1 V max clamping at 2.3 A peak pulse); the datasheet numbers this as the anode end only for uni-directional parts, and the bi-directional symbol is symmetric. |
