BZW50-39 from STMicroelectronics, in a R6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | passive | Anode terminal of the unidirectional TVS diode. In the R6 axial package this is one of the two leads; the cathode is identified by the cathode bar marking on the body. |
| 2 | K | passive | Cathode terminal of the unidirectional TVS diode. Identified by the printed cathode bar on the body (unidirectional devices only, per Figure 14 marking layout). |
