SMF120CA 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 | Bidirectional TVS terminal with no polarity (the C suffix denotes bi-directional); for SMF120CA the reverse standoff voltage is 120 V and the breakdown voltage is 133 V min to 147 V max at 1.0 mA. |
| 2 | 2 | passive | Bidirectional TVS terminal with no polarity and no cathode band; for SMF120CA the max clamping voltage is 193 V at 1.1 A peak pulse current and max leakage is 5.0 uA at VRWM. |
