unidirectional-blocking low-capacitance ABD
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.
