NOTE:
1. TOLERANCE AND VOLTAGE DESIGNATION - The JEDEC type numbers shown indicate a tolerance of+/-10% with
guaranteed limits on only Vz, I
R
, I
r
, and V
F
as shown in the electrical characteristics table. Units with guaranteed limits
on all seven parameters are indicated by suffix “B” for+/-5% tolerance.
2. ZENER VOLTAGE (Vz) AND IMPEDANCE (Z
ZT
& Z
ZK
) - Test conditions for Zener voltage and impedance are as
follows; Iz is applied 40+/-10 ms prior to reading. Mounting contacts are located from the inside edge of mounting
clips to the body of the diode(Ta=25
C
)

3. SURGE CURRENT (Ir) - Surge current is specified as the maximum allowable peak, non-recurrent square-wave
current with a pulse width, PW, of 8.3 ms. The data given in Figure 5 may be used to find the maximum surge
current for a quare wave of any pulse width between 1 ms and 1000ms by plotting the applicable points on
logarithmic paper. Examples of this, using the 6.8v ,
is
shown in Figure 6. Mounting
contact located as specified in Note 3. (T
A
=25
).
4. VOLTAGE REGULATION (Vz) - Test conditions for voltage regulation are as follows: Vz measurements are made
at 10% and then at 50% of the Iz max value listed in the electrical characteristics table. The test currents are the
same for the 5% and 10% tolerance devices. The test current time druation for each Vz measurement is 40+/- 10 ms.
(T
A
=25C ). Mounting contact located as specified in Note2.
5. MAXIMUM REGULATOR CURRENT (I
ZM
) - The maximum current shown is based on the maximum voltage of a
5% type unit. Therefore, it applies only to the B-suffix device. The actual I
ZM
for any device may not exceed the
value of 5 watts divided by the actual Vz of the device. T
L
=75Cat maximum from the device body.
APPLICATION NOTE:
Since the actual voltage available from a given Zener
diode is temperature dependent, it is necessary to determine
junction temperature under any set of operating conditions
in order to calculate its value. The following procedure is
recommended:
Lead Temperature, T
L
, should be determined from:
T
L
=
q
LA
P
D
+ T
A
For worst‐case design, using expected limits of I
Z
, limits
of P
D
and the extremes of T
J
(DT
J
) may be estimated.
Changes in voltage, V
Z
, can then be found from:
DV
=
q
VZ
DT
J
q
LA
is the lead‐to‐ambient thermal resistance and P
D
is the
power dissipation.
Junction Temperature, T
J
, may be found from:
T
J
= T
L
+
DT
JL
DT
JL
is the increase in junction temperature above the lead
temperature and may be found from Figure 4 for a train of
power pulses or from Figure 1 for dc power.
DT
JL
=
q
JL
P
D
q
VZ
, the Zener voltage temperature coefficient, is found
from Figures 2 and 3.
Under high power‐pulse operation, the Zener voltage will
vary with time and may also be affected significantly by the
zener resistance. For best regulation, keep current
excursions as low as possible.
Data of Figure 4 should not be used to compute surge
capability. Surge limitations are given in Figure 5. They are
lower than would be expected by considering only junction
temperature, as current crowding effects cause temperatures
to be extremely high in small spots resulting in device
degradation should the limits of Figure 5 be exceeded.
