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, and D denotes a ± 1% tolerance. The electrical characteristics are measured after allowing the device to stabilize for 20 seconds when
mounted on a heat sink.
Note 2.
The zener impedance is derived from the 60 Hz ac voltage, which results when an ac current having an r.m.s. valued equal to 10% of the dc
zener current (I
ZT
or I
ZK
) is superimposed on I
ZT or
I
ZK.
Zener impedance is measured at two points to insure a sharp knee on the breakdown
curve, thereby eliminating unstable units.
