BZT52C6V8SQ from JSMSEMI, in a SOD-323. 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 of the zener diode (pin 1), which is the reverse-biased side for regulation; BZT52C6V8SQ has VZ 6.46-7.14 V (6.80 V typ) at IZT = 5 mA. |
| 2 | Anode | passive | Anode of the zener diode (pin 2); forward voltage is 0.9 V at IF = 10 mA. |
