NOTE1 The JEDEC type numbersshown(B suffix) have a
±5% tolerance on nominal zener voltage. The suffix A is used
to identify ± 10% tolerance; no suffix indicates ±20% tol-
erance. If tighter tolerance is required, consult factory.
Standard polarity units have the anode connected to the case.
Reverse polarity (cathode-to-case) units are available and are
indicated by suffixing an R to the part number.
NOTE 2 Zener Voltage (V
z
) is measured with junction in
thermal equilibrium with 30°C base temperature. The test
currents
(\zj)
have been selected so that at nominal voltages
the dissipation is a constant 12.5 watts. This results in a
nominal junction temperature rise of I8J5°C.
NOTE 3 The zener impedance is derived from the 60 cycle
A.C. voltage, which results when an A.C. current having an
R.M.S. value equal to 10% of the D.C. zener current (I
a
or
l
z
l,) is superimposed on 1^ or I
z
(,. Zener impedance is measured
at 2 points to insure a sharp knee on the breakdown curve and
to eliminate unstable units. A curve showing the variation of
zener impedance vs. zener current for six representative types
is shown in Figure 3. A 100% cathode ray tube curve trace
test is used to insure that each zener diode breakdown region
begins at a current lower than I
z
k and continues at nearly
constant voltage to a current level in excess of I
2m
•
NOTE 4 The values of I
zm
are calculated for a ±5% toler-
ance on nominal zener voltage. Allowance has been made for
the rise in zener voltage above V
rt
which results from zener
impedance and the increase in junction temperature as power
dissipation approaches 50 watts. In the case of individual
diodes I
zm
is that value of current which results in a dissipa-
tion of 50 watts.
