All devices are rated at
10W
Zener impedance is derived from 60Hz AC voltage which results when AC current RMS value (which equals 10%
of the DC zener current) is superimposed on I
Z
•
Zener impedance is measured at two points on the reverse breakdown curve
•
I
ZM
values are derived for a ±5% V
Z
tolerance
Standard voltage tolerances are ±5% (B suffix), ±10% (A suffix) & ±20% (no suffix)
