AZ23C39 from Yangzhou Yangjie Elec Tech, in a SOT-23(TO-236). 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 | K1 | passive | Cathode of zener diode 1, which has a nominal zener voltage of 39 V (37 V min, 41 V max at IZT = 2 mA) for AZ23C39. |
| 2 | K2 | passive | Cathode of zener diode 2, which has a nominal zener voltage of 39 V (37 V min, 41 V max at IZT = 2 mA) for AZ23C39, and the two diodes match within 5% in VZ. |
| 3 | A | passive | Common anode of both zener diodes, which is the single lead on the top side of the SOT-23 package. |
