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.
