BZX84C22LT1G
onsemi · Zener Diodes · SOT-23
BZX84C22LT1G 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's SOT-23 Style 8 pinout assigns pin 1 as the anode, and the cathode is marked by a polarity band. |
| 2 | No Connection | unconnected | Pin 2 is not connected internally and is listed as 'No Connection' in the SOT-23 Style 8 pinout. |
| 3 | Cathode | passive | Cathode of the Zener diode; the datasheet's SOT-23 Style 8 pinout assigns pin 3 as the cathode, which is the terminal the polarity band marks. |
