MCC Micro Commercial Components · Zener Diodes · SOT-23
BZX84C30-TP from MCC Micro Commercial Components, 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, shown connected to the diode symbol in the Internal Structure drawing (forward voltage VF 0.9V max at IF=10mA). |
| 2 | NC | unconnected | Pin 2 appears in the Internal Structure drawing with no connection to the diode, so it is treated as not connected. |
| 3 | K | passive | Cathode of the zener diode, shown tied to the diode bar in the Internal Structure drawing; the BZX84C30 has a nominal VZ of 30.00V (28.00V to 32.00V) at IZT=2mA. |
