BZX84C68LT1G

onsemi · Zener Diodes · SOT-23-3

BZX84C68LT1G from onsemi, in a SOT-23-3. 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 terminal of the Zener diode; the cathode is identified by the polarity band on the package.
2 NC unconnected No internal connection; the pin is not connected to the Zener diode.
3 Cathode passive Cathode terminal of the Zener diode, marked by the polarity band, which sets the regulated reverse breakdown voltage (VZ 64 V min to 72 V max for BZX84C68LT1G).
