FUXINSEMI · ESD And Surge Protection (TVS/ESD) · SOD-123
SMF30CA from FUXINSEMI, 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 (no polarity) for SMF30CA with 30 V reverse standoff, 33.3-36.8 V breakdown at 1.0 mA and 48.4 V max clamping at 4.2 A Ipp; the datasheet labels this pin 'cathode' only for unidirectional parts. |
| 2 | 2 | passive | Bidirectional TVS terminal (no polarity) for SMF30CA with 30 V reverse standoff, 33.3-36.8 V breakdown at 1.0 mA and 48.4 V max clamping at 4.2 A Ipp; the datasheet labels this pin 'anode' only for unidirectional parts. |
