The device numbers listed have a standard tolerance on the nominal zener voltage of
±2%.
Device tolerance of
±5%
is
indicated by a “C” instead of a “B”.
For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter
voltage tolerances, contact your nearest
YEASHIN
representative.
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.
