AZ23C39

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

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.
