AZ23C43 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 (AZ23C43 nominal Vz 43 V at 5 mA, 40.85-45.15 V range), the other diode of the dual common-anode pair is on pin 2. |
| 2 | K2 | passive | Cathode of zener diode 2 (AZ23C43 nominal Vz 43 V at 5 mA), with Vz matched within 5% of the diode on pin 1. |
| 3 | A | passive | Common anode of both zener diodes in the dual common-anode configuration, with total power dissipation rated at 300 mW. |
