**PANJIT International** · TVS · SMB(DO-214AA)

P6SMBJ40A_R2_00001 from PANJIT International, in a SMB(DO-214AA). 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 | K | passive | Cathode terminal, marked by the color band on the unidirectional P6SMBJ40A (VRWM 40 V, breakdown 44.4 to 49.1 V at 1 mA, max clamp 64.5 V at 9.3 A). |
| 2 | A | passive | Anode terminal of the unidirectional P6SMBJ40A, the end opposite the color band, with 600 W peak pulse power on a 10/1000μs waveform. |
