BZT52-C6V8X from Nexperia, in a SOD-123. 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, identified by the marking bar; the Zener reverse-breakdown terminal (VZ 6.4 V to 7.2 V at IZ = 5 mA for BZT52-C6V8), and the solder point of the cathode tab. |
| 2 | A | passive | Anode; forward current is limited to 250 mA with VF max 0.9 V at IF = 10 mA. |
