Notes: 1) The Zener Impedance is derived from the 60 Hz AC voltage which
results when an AC current having an RMS value equal to 10% of the
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 to eliminate unstable units.
2) Standard Zener voltage tolerance is ±20%. Add suffix “A” for
±10% Tolerance, suffix “B” for ±5 tolerance, suffix “C” for ±2%
tolerance, Other tolerance, non standard and higher Zener voltages
are upon request.
3)Valid provided that leads at a distance of 8 mm from case are kept
at ambient temperature.
4) Measured under thermal equilibrium and DC test conditions.
5) Tested with pulses tp = 20 ms.
6) VF(Max)=1.10V@ IF=200mA
