DEFINITION

Classification: 257/121

With diode or transistor in reverse path:

(under subclass 119) Subject matter wherein a diode (i.e., a device which passes current in only one direction) is

connected to conduct current in one direction, with a regenerative switching device with a control electrode connected to conduct current in the other direction to produce a bi-directionally conducting regenerative switching device.
