Type
The zener voltage (V
The device numCers listed have a standard tolerance on the nominal zener voltage of ±2%.
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 (I
For detailed information on price, availaCility and delivery of nominal zener voltages Cetween the voltages shown and tighter
