WebZener impedance is the equivalent series resistance of a Zener diode when it is conducting current. Zener impedance should ideally be zero, but in reality, a Zener diode has some … WebAvalanche photodiodes are photodiodes with structure optimized for operating with high reverse bias, approaching the reverse breakdown voltage. This allows each photo-generated carrier to be multiplied by avalanche breakdown , resulting in internal gain within the photodiode, which increases the effective responsivity of the device.
