BZX84C3V3-7-F
Diodes Incorporated · Zener Diodes · SOT-23
BZX84C3V3-7-F from Diodes Incorporated, 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 lower-left terminal in the top-view device schematic. |
| 2 | NC | unconnected | Lower-right terminal, which the device schematic shows with no internal connection. |
| 3 | K | passive | Cathode of the Zener diode, the single top terminal in the schematic. The BZX84C3V3 has a Zener voltage of 3.1V to 3.5V (3.3V nominal) at IZT = 5.0mA. |
