VF Forward Voltage = 900mV Maximum @ IF = 10 mA for all types
Notes:
1.
The zener voltage (VZ) is tested under pulse condition of 1mS.
2.
The device numCers listed have a standard tolerance on the nominal zener voltage of ±2%.
3.
The zener impedance is derived from the 60-cycle 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 to IZT or IZK.
