unidirectional-blocking low-capacitance ABD

A two-terminal device that has at least one unidirectional ABD with at least one rectifier p-n junction connected in series in the opposite polarity in order to reduce capacitance.

NOTE    The unidirectional-blocking low-capacitance ABD is intended to suppress transients in only one direction. The rectifier p-n junction(s) have low capacitance and block in the reverse direction; they are not intended to be operated in their reverse avalanche breakdown regions. The p-n junction that serves as the unidirectional ABD determines which terminal is the anode and which is the cathode; for that determination, the rectifier p-n junction is ignored.
