3. The type numbers shown have a standard tolerance of
±5%
on the nominal Zener voltage.
4. Nominal Zener voltage is measured with the device junction in thermal equilibrium at T
L
= 30°C
$1°C.
5. Z
ZT
and Z
ZK
are measured by dividing the AC voltage drop across the device by the ac current applied.
The specified limits are for I
Z(AC)
= 0.1 I
Z(dc)
with the AC frequency = 1 KHz.
*The “G’’ suffix indicates Pb−Free package available.
