# SMF7.0A-HAF

**EIC Semicon** · ESD And Surge Protection (TVS/ESD) · SOD-123FL

SMF7.0A-HAF from EIC Semicon, in a SOD-123FL. 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 | Cathode | passive | Cathode terminal of the TVS diode, per the PINNING table on the SOD-123FL outline; the datasheet gives no separate electrical limit for this pin, and the family ratings apply (SMF7.0A stand-off voltage VWM 7 V, breakdown VBR 7.8 V min to 8.6 V max at IT 10 mA). |
| 2 | Anode | passive | Anode terminal of the TVS diode, per the PINNING table on the SOD-123FL outline; the datasheet gives no separate electrical limit for this pin, and the absolute maximum ratings apply (peak pulse power PPPM 200 W, junction and storage temperature −55 to +150 ℃). |
