AZ23C20

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

AZ23C20 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 (nominal VZ 20 V at IZT = 5 mA for AZ23C20, range 18.8 to 21.2 V).
2 K2 passive Cathode of zener diode 2 (nominal VZ 20 V at IZT = 5 mA for AZ23C20), matched to diode 1 within 5% VZ.
3 A passive Common anode of both zener diodes (dual zeners in common anode configuration).
