# SMAJ5.0A-TP

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

SMAJ5.0A-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 | Cathode | passive | Cathode terminal, marked by the cathode band on unidirectional devices; connect to the positive side of the protected line (reverse stand-off voltage VWM 5.0V for SMAJ5.0A). |
| 2 | A | passive | Anode terminal of the unidirectional TVS diode; connect to ground/return side of the protected line. |
