P6SMBJ78A 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, the end marked by the color band; for the unidirectional P6SMBJ78A this is the terminal that goes positive relative to the anode, with VRWM 78 V, breakdown 86.7 to 95.8 V at 1 mA, and max clamp 126 V at 4.7 A (10/1000μs). |
| 2 | A | passive | Anode, the terminal opposite the color band; the 600 W (10/1000μs) transient suppressor conducts forward from here to the cathode, with a peak forward surge current of 100 A (8.3 ms half sine). |
