SYMBOLS & DEFINITIONS
Symbol
Definition
VZ
Zener Voltage: The zener voltage the device will exhibit at a specified current (IZ) in its breakdown region.
IZ, IZT, IZK
Regulator Current: The dc regulator current (IZ), at a specified test point (IZT), near breakdown knee (IZK).
ZZT or ZZK
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 IZT or IZK) and superimposed on IZT or IZK respectively.
VF
Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
IR
Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and
temperature.
IZM
Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating.
IZSM
Maximum Zener Surge Current: The nonrepetitive peak value of zener surge current at a specified wave form.
