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
