Notes:
1. Nominal Zener Voltage (V_Z) is read with the device in standard test clips with 3/8- to 1/2-inch spacing between clip and case
of the diode. Before reading, the diode is allowed to stabilize for a period of 40 ±10 milliseconds at 25°C +8, -2°C.
2. The Zener Impedance (Z_Z or Z_ZK) is derived from the 60 Hz ac voltage, which results when an ac current having an rms
value equal to 10% of the dc zener current (I_ZT or I_ZK) is superimposed on I_ZT or I_ZK, respectively.
3. The Surge Current (I_ZSM) is specified as the maximum peak of a nonrecurrent sine wave of 8.3 milliseconds duration.
4. Voltage regulation (DV_Z) is the difference between the voltage measured at 10% and 50% of I_ZM.
