NOTE 1
The JEDEC type numbers shown have A 5% tolerance on nominal zener voltage.
No suffix signifies A 10% tolerance, C signifies 2%, and D signifies 1% tolerance.
NOTE 2
The zener impedance is derived from the 60Hz AC voltage, which results when an AC current having an rms value equal to
10% of the DC zener current (Izt or Izk) is superimposed on Izt or Izk. Zener impedance is measured at two points to insure
a sharp knee on the breakdown curve and eliminate unstable units.
NOTE 3
The reverse surge current is measured at 25
o
C ambient using a 1/2 square wave or equivalent sine wave pulse 1/120 second
duration superimposed on Izt
NOTE 4
Voltage measurements to be performed 90 seconds after application of DC current.
