Notes:

1. The Zener Voltage (VZ) is tested under pulse condition of 1ms.

2. The device numbers listed have a standard tolerance on the nominal zener voltage of ±5%.

4. 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.
