Notes:
1. The Zener Voltage (V
Z
) is tested under pulse condition of 10ms.
2. The device numbers listed have a standard tolerance on the nominal zener voltage of ±5%.
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
ZT
or I
ZK
) is superimposed to I
ZT
or I
ZK
.
