Definition
Zener Voltage: The zener voltage the device will exhibit at a specified current (I
Z
) in its breakdown region.
Regulator Current: The dc regulator current (I
Z
), at a specified test point (I
ZT
), or near breakdown knee (I
ZK
).
Dynamic Impedance: The small signal impedance of the diode when biased to operate in its breakdown region
at a specified rms current modulation (typically 10% of I
ZT
or I
ZK
) and superimposed on I
ZT
or I
ZK
respectively.
Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and
temperature.
Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating.
Maximum Zener Surge Current: The nonrepetitive peak value of zener surge current at a specified wave form.
