# SMA6J20A-TP

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

SMA6J20A-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 of the unidirectional TVS, marked by the cathode band; SMA6J20A has VWM 20 V, VBR 22.2-24.5 V at 1 mA and max clamping voltage 32.4 V at 18.5 A. |
| 2 | Anode | passive | Anode terminal of the unidirectional TVS, opposite the cathode band end; SMA6J20A has 600 W minimum peak pulse power (10/1000us). |
