# SMAJ58CA-TP

**MCC(Micro Commercial Components)** · TVS · DO-214AC(SMA)

SMAJ58CA-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 | Bi-directional (CA suffix) TVS terminal with no polarity and no cathode band; the part clamps at 93.6 V max at 4.3 A IPP and has VWM of 58 V. |
| 2 | A2 | passive | Second bi-directional TVS terminal, interchangeable with the other terminal; breakdown is 64.4 V to 71.2 V at 1 mA. |
