Notes:

4.
The zener voltage (V
Z
) is tested under pulse condition of 1mS.
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
ZT
or
I
ZK
) is superimposed to
I
ZT
or
I
ZK.
For detailed information on price, availaCility and delivery of nominal zener voltages Cetween the voltages shown and tighter
voltage tolerances, contact your nearest Tak Cheong Electronics representative.
