Notes: 1. Tolerance and voltage designation: the type numbers listed have zener voltage as shown.
2. Specials available include: nominal zener voltages between the voltages shown and
tighter voltage, for detailed information on price, availability and delivery.
3. Zener voltage (V
Z
) measurement: the zener voltage is measured under pulse conditions
such that T
J
is more than 2
o
C above T
A
.
4. Zener impedance (Z
Z
) derivation: 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
) is superimposed to IZT.
