BZX84B5V1Q-7-F

Diodes Incorporated · Zener Diodes · SOT-23-3

BZX84B5V1Q-7-F from Diodes Incorporated, in a SOT-23-3. 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, shown on the bottom-left lead of the device schematic.
2 NC unconnected No internal connection; the device schematic shows this lead with no connection to the diode.
3 K passive Cathode of the zener diode, shown on the single top lead of the device schematic; it is the positive terminal in reverse-breakdown operation.
