SMAJ7.0CA-TP from MCC(Micro Commercial Components), in a DO-214AC(SMA). 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 (SMAJ7.0CA: 7.0 V stand-off, 7.78-8.60 V breakdown at 10 mA, 12.0 V max clamping at 33.3 A) with no polarity, interchangeable with the other terminal and with no cathode band. |
| 2 | A2 | passive | Bidirectional TVS terminal (400 W min peak pulse power at 10/1000 us) with no polarity, interchangeable with the other terminal; the datasheet says the cathode band is not used on bi-directional types. |
