BZX84C5V1Q

Yangzhou Yangjie Elec Tech · Zener Diodes · SOT-23

BZX84C5V1Q from Yangzhou Yangjie Elec Tech, in a SOT-23. 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 left of the diode symbol on the SOT-23 pin diagram.
2 NC unconnected Pin 2 is drawn with no connection to the diode in the SOT-23 pin diagram.
3 K passive Cathode of the Zener diode, which regulates at VZ 4.8V min / 5.1V typ / 5.4V max at IZT=5mA for the BZX84C5V1Q.
