# BZV55C3V3

**LGE** · Zener Diodes · SOD-80

BZV55C3V3 from LGE, in a SOD-80. 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, marked by the blue color band; the zener is reverse-biased with this terminal positive (VZ 3.1 to 3.5 V at 5 mA). |
| 2 | A | passive | Anode (positive) terminal at the end opposite the blue band; forward voltage is 1.0 V maximum at IF=100 mA. |
