DEFINITION

Classification: 327/194

Zener or capacitive diode:

(under subclass 185) Subject matter including a diode having a threshold voltage above which the applied voltage must rise before the diode junction breaks down allowing the current flow across the junction to suddenly rise or including a voltage responsive two terminal semiconductor device whose capacitance varies as a result of changes in the space charge at a pn junction.
