BZX84C4V7A

Shandong Jingdao Microelectronics · Zener Diodes · SOT-23

BZX84C4V7A from Shandong Jingdao Microelectronics, 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 single zener diode (Suffix A); BZX84C4V7A has 4.7V nominal zener voltage (4.61V to 4.79V Min to Max) and 350mW maximum power dissipation.
2 NC unconnected No internal connection on the single-diode Suffix A device; the package drawing shows no diode connected to pin 2.
3 K passive Cathode of the single zener diode (Suffix A); forward voltage is 0.9V at IF = 10mA.
