LGE · Zener Diodes · SOD-80
BZV55B4V7 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, marked by the blue color band indicating negative polarity; Zener voltage for BZV55B4V7 is 4.61 to 4.79 V at IZT = 5 mA. |
| 2 | A | passive | Anode terminal (positive side); the datasheet gives forward voltage of 1.0 V maximum at IF = 100 mA and 500 mW maximum power dissipation. |
