BZT52B33 from Shikues, 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 | Cathode | passive | Cathode terminal of the zener diode, labeled pin 1 on the SOD-123 outline and symbol; the datasheet gives no separate electrical limit for this pin beyond the device ratings (Ptot 500 mW, Tj/Tstg -55 to +150 °C). |
| 2 | Anode | passive | Anode terminal of the zener diode, labeled pin 2 on the SOD-123 outline and symbol; the datasheet gives no separate electrical limit for this pin beyond the device ratings (Ptot 500 mW, Tj/Tstg -55 to +150 °C). |
