BZX84C3V6WQ
Yangzhou Yangjie Elec Tech · Zener Diodes · SOT-323(SC-70)
BZX84C3V6WQ from Yangzhou Yangjie Elec Tech, in a SOT-323(SC-70). 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 | Zener anode, drawn on page 1 as the terminal on the input side of the diode symbol; the 3.6V (3.4V to 3.8V at 5mA) zener regulation is measured with the cathode positive relative to this pin. |
| 2 | NC | unconnected | Pin 2 is drawn in the page 1 internal diagram with no connection to the diode, so it is a no-connect terminal. |
| 3 | K | passive | Zener cathode, drawn on page 1 at the bar side of the diode symbol; it is the pin that goes positive for reverse zener regulation (VZ 3.4V to 3.8V at IZT 5mA). |
