NZH20C

Nexperia · Zener Diodes · SOD-123F

NZH20C from Nexperia, in a SOD-123F. 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 K passive Cathode of the Zener diode, indicated by the marking bar; NZH20C has VZ 19.23 V to 20.22 V at IZ = 10 mA.
2 A passive Anode of the Zener diode; forward voltage is at most 0.9 V at IF = 10 mA.
