DZ23C27Q 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 | A1 | passive | Anode of zener diode 1; the symbol on page 1 shows the two diodes sharing a common cathode at pin 3, with each diode rated at VZ 25.1V to 28.9V (27V typ) at 2 mA. |
| 2 | A2 | passive | Anode of zener diode 2; the symbol on page 1 shows the two diodes sharing a common cathode at pin 3, with each diode rated at VZ 25.1V to 28.9V (27V typ) at 2 mA. |
| 3 | K | passive | Common cathode of both zener diodes; power dissipation is 300 mW with a single diode loaded. |
