DEFINITION

Classification: 327/500

"S"-shape curve on I-V plot (e.g., pnpn diode type, etc.):

(under subclass 498) Subject matter including a solid-state device whose characteristic on a current versus voltage plot (i.e., with the current plotted on the Y axis and voltage on the X axis) has an "S"-shape.
