BZX84C3V3 from hongjiacheng, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | passive | Anode of Zener diode; positive terminal for forward conduction; polarity determined by cathode-line marking on package per page 1 mechanical data note. |
| 2 | K | passive | Cathode of Zener diode; nominal reverse Zener voltage 3.3 V (min 3.1 V, max 3.5 V) at IZT = 5 mA; ZZT = 95 Ω; IR = 5.0 µA at VR = 1.0 V. |
| 3 | K | passive | Second cathode connection, internally shorted to pin 2; package dissipation rating 300 mW (Ta = 25 °C, RθJ-A = 417 °C/W). |
