BZX84C15Q-13-F

Diodes Incorporated · Zener Diodes · SOT-23-3

BZX84C15Q-13-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 15V Zener (BZX84C15, VZ 13.8V to 15.6V at IZT = 5.0mA), the lower-left lead in the top-view device schematic.
2 NC unconnected Lower-right lead, drawn with no internal connection in the device schematic.
3 K passive Cathode of the Zener diode, the single top lead in the device schematic, which goes positive in reverse breakdown.
