NOTE1
1N3993-1N4000 series: suffix A indicates ±5%
tolerance, no suffix indicates±10% tolerance. 1N2970-1N3015
series: suffix B indicates ±5% tolerance, suffix A indicates
+ 10%, no suffix indicates ±20% tolerance. If tighter tolerance
is required, consult factory.
NOTE 2 The electrical characteristics are measured after
allowing the device to stabilize for 90 seconds with 30°C Base
temperature.
superimposed on I^j or IZK- When making zener impedance
measurements at the I
z
n test point, it may be necessary to
insert a 60 Hz band pass filter between the diode and voltmeter
to avoid errors resulting from low level noise signals. A curve
showing the variation of zener impedance vs. zener current for
three representative types is shown in Figures 3 and 4.
NOTE 4 These values of !„„ may be exceeded in the case
of individual diodes. The values shown are calculated for the
worst case which is a unit of ±5% tolerance at the high
voltage end of its tolerance range. Allowance has also been
made for the rise in zener voltage above
V
a
,
which results
from zener impedance and the increase in junction tempera-
ture as power dissipation approaches 10 watts.
NOTE 3 The 7.ener impedance (Zzr) 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 (Izj or IZK) is
