unidirectional-conducting low-capacitance ABD

A two-terminal device comprising a unidirectional-blocking low-capacitance ABD and an anti-parallel diode.

NOTE    To create a low-capacitance ABD with a forward-conducting, low-voltage characteristic, a low-capacitance diode (such as a rectifier) is placed in anti-parallel to the unidirectional-blocking low-capacitance ABD. This diode must have a reverse blocking voltage greater than the avalanche breakdown voltage of the unidirectional ABD.
