BZV55C3V9

LGE · Zener Diodes · SOD-80

BZV55C3V9 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 polarity terminal), marked by the blue color band; the zener voltage VZ for BZV55C3V9 is 3.7 V min to 4.1 V max at IZT = 5 mA.
2 A passive Anode terminal, opposite the blue color band; forward voltage is 1.0 V maximum at IF = 100 mA.
