BZX84C39Q-7-F

Diodes Incorporated · Zener Diodes · SOT-23

BZX84C39Q-7-F from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode of the Zener diode. In normal Zener regulation operation this pin is biased positive relative to the anode; at breakdown (VZ ≈ 39V) it clamps the reverse voltage. Forward drop VF ≈ 0.9V @ IF = 10mA.
2 A passive Anode of the Zener diode. Ground/return side in a shunt-regulator configuration. Forward drop VF ≈ 0.9V @ IF = 10mA in the forward direction (A to K).
3 NC unconnected No internal connection on the Diodes Inc BZX84 SOT-23 single-Zener package. Leave floating or tie to cathode net; do not use as a signal node.
