**MCC(Micro Commercial Components)** · TVS · SMB

SMBJP6KE300A-TP from MCC(Micro Commercial Components), in a SMB. 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 of the unidirectional TVS, marked by the color band/cathode mark and taken as the positive end; the part is stand-off rated for VWM 256V with 285-315V breakdown at 1mA. |
| 2 | Anode | passive | Anode of the unidirectional TVS (SMBJP6KE300A), the end opposite the cathode band, with a maximum forward voltage of 1.5V at 1A. |
