SZBZX84C22LT1G

onsemi · Zener Diodes · SOT-23

SZBZX84C22LT1G from onsemi, in a SOT-23. 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 ANODE passive Anode of the Zener diode; the datasheet pinout is 1-Anode, 2-No Connection, 3-Cathode for this series.
2 NC unconnected No connection; this pin is not internally connected on the SOT-23 package.
3 CATHODE passive Cathode of the Zener diode, indicated by the polarity band on the package; nominal Zener voltage VZ is 22 V (20.8 V min to 23.3 V max at IZT = 5 mA) with 250 mW total power dissipation rating on FR-5 board.
