# AZ23C24

**Yangzhou Yangjie Elec Tech** · Zener Diodes · SOT-23(TO-236)

AZ23C24 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 (AZ23C24 nominal VZ 24 V, 22.8 V min to 25.6 V max at IZT = 5 mA). |
| 2 | K2 | passive | Cathode of zener diode 2 (AZ23C24 nominal VZ 24 V, 22.8 V min to 25.6 V max at IZT = 5 mA), matched to diode 1 within 5% VZ. |
| 3 | A | passive | Common anode of both zener diodes, shared by pins 1 and 2 (dual zeners in common anode configuration). |
