BZX84C3V0W-7-F

Diodes Incorporated · Zener Diodes · SOT-323

BZX84C3V0W-7-F from Diodes Incorporated, in a SOT-323. 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 A passive Anode of the Zener diode, the lower-left lead in the device schematic, connected to the diode triangle; Zener voltage 2.8V min to 3.2V max at IZT = 5mA for the BZX84C3V0W.
2 NC unconnected Lower-right lead in the device schematic, drawn with no internal connection to the diode.
3 K passive Cathode of the Zener diode, the single top lead in the device schematic, connected to the diode bar; power dissipation is 200mW maximum.
