SYMBOLS & DEFINITIONS

Definition

Zener Voltage: The zener voltage the device will exhibit at a specified current (IZ) in its breakdown

region.

Regulator Current: The dc regulator current (IZ), at a specified test point (IZT), near breakdown knee

(IZK).

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.

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.

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.
