BZW50-180B from STMicroelectronics, in a R-6. 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 | 1 | passive | Bidirectional TVS terminal (BZW50-180B, VRM 180 V, VBR min 200 V at 1 mA), interchangeable with the other lead and with no polarity; red tape on both sides in tape packing. |
| 2 | 2 | passive | Bidirectional TVS terminal (BZW50-180B, VRM 180 V, VBR min 200 V at 1 mA), interchangeable with the other lead and with no polarity; red tape on both sides in tape packing. |
