# BZX55C16

**LGE** · Zener Diodes · DO-35

BZX55C16 from LGE, in a DO-35. 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, the lead on the polarity-band end of the DO-35 body; it goes positive relative to the anode in zener regulation (VZ 15.3 to 17.1 V at IZT = 5.0 mA for BZX55C16). |
| 2 | A | passive | Anode, the lead opposite the polarity band; forward voltage is at most 1.0 V at IF = 100 mA. |
