I ZM
I ZSM 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 ), 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 non-repetitive peak value of Zener surge current at a specified wave form. T4-LDS-0183, Rev. 3 (120901) ©2012 Microsemi Corporation Page 2 of 6
