P6SMB550CA from YFW, 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 | Cathode | passive | Cathode terminal per the datasheet pinning table; for the bidirectional CA part the device is symmetric, with 468 V reverse stand-off and 522.5-577.5 V breakdown at 1 mA. |
| 2 | Anode | passive | Anode terminal per the datasheet pinning table; for the bidirectional CA part the device is symmetric, with 600 W peak pulse power (10/1000 µs) and 760 V max clamping voltage at 0.8 A. |
