Also available in 2% and 1% tolerance, suffix C and D respectively. VZ is measured with the diode in thermal equilibrium in 25 OC still air. 2) Zener impedance is derived by superimposing on IZT, a 60 Hz rms a.c. current equal to 10% of IZT (25 μA a.c.). 3) Tested with pulses tp = 20 ms.

Actual measurement is performed using a 1KHz to 8KHz frequency bandpass filter at a constant Zener test current(I ZT) at 25 C ambient temperature. N D is calculated from the formula.
