BZV55C33 from LGE, in a LL-34. 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 (negative terminal), identified by the blue color band on the LL-34 body; the zener voltage for BZV55C33 is 31 V min to 35 V max at IZT = 2 mA. |
| 2 | A | passive | Anode (positive terminal) at the end opposite the blue color band; forward voltage is 1.0 V maximum at IF = 100 mA and total power dissipation is 500 mW. |
