Note
1: No suffix indicates a 20% tolerance on nominal V
Z
, Suffix A denotes a 10% tolerance, B denotes a 5%
tolerance, C denotes a 2% tolerance.
o
2: Zener voltage(V
Z
) measured at T
L
= 30 C. Voltage measurement to be performed 20 seconds after
application of DC current.
3: The Zener impedance is derived from the 60 Hz 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 on I
