BZV55B3V0

LGE · Zener Diodes · LL-34

BZV55B3V0 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 polarity terminal, marked by the blue color band); BZV55B3V0 regulates at VZ 2.94 V min to 3.06 V max at IZT = 5 mA within a 500 mW total power dissipation limit.
2 A passive Anode terminal (end opposite the blue color band); forward voltage is 1.0 V maximum at IF = 100 mA.
