MDD(Microdiode Electronics) · Zener Diodes · SOT-23
BZX84C22 from MDD(Microdiode Electronics), 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 | A | passive | Anode of the Zener diode; the page 1 symbol shows the diode arrow pointing from pin 1 toward pin 3. |
| 2 | NC | unconnected | No connection; the page 1 symbol draws pin 2 as an open terminal with no link to the diode. |
| 3 | K | passive | Cathode of the Zener diode; for BZX84C22, VZ is 22 V nominal (20.8 to 23.3 V) at IZT = 5 mA. |
