P6SMB22A from MSKSEMI, in a DO-214AA(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 | K | passive | Cathode of the unidirectional P6SMB22A, which stands off 18.80V VRWM, breaks down at 20.90~23.10V at 1mA and clamps at 30.6V at 19.9A peak pulse current. |
| 2 | A | passive | Anode of the unidirectional P6SMB22A, the reference terminal for the 600W (10/1000μs) peak pulse power rating and the forward direction (VF 3.5V max at 50A for VBR up to 200V). |
