Notes:

1. The zener voltage (V ) is tested under pulse condition of 1ms.

Z

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 (I

or I ) is superimposed to I

or I .
