BZT52C3V3-E3-18 from Vishay Intertech, in a SOD-123. 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 | K | passive | Cathode, marked by the cathode bar on the package; the BZT52C3V3 Zener voltage is 3.1 V min, 3.3 V nom and 3.5 V max at IZT1 = 5 mA. |
| 2 | A | passive | Anode, the terminal opposite the cathode bar; the maximum power dissipation is 500 mW on a ceramic substrate with 5 mm2 pad areas. |
