NOTE:  
1. TOLERANCE AND VOLTAGE DESIGNATION - The JEDEC type numbers shown indicate a tolerance of+/-10% with  
guaranteed limits on only Vz, IR, Ir, and VF 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 (ZZT & ZZK) - 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  
qC  
clips to the body of the diode(Ta=25  
)

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  
ć
contact located as specified in Note 3. (TA=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.  
(TA=25C ). Mounting contact located as specified in Note2.  
5. MAXIMUM REGULATOR CURRENT (IZM) - 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 IZM for any device may not exceed the  
value of 5 watts divided by the actual Vz of the device. TL=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:  
For worst‐case design, using expected limits of I , limits  
Z
of P and the extremes of T (DT ) may be estimated.

Changes in voltage, V , can then be found from:  
Z
DV = qVZ DTJ  
q
, the Zener voltage temperature coefficient, is found  
VZ  
from Figures 2 and 3.  
Lead Temperature, T , should be determined from:  
L
TL = qLA PD + TA  
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.

D
LA  
Junction Temperature, T , may be found from:  
J
TJ = TL + DTJL  
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.  
DT is the increase in junction temperature above the lead  
JL  
temperature and may be found from Figure 4 for a train of  
power pulses or from Figure 1 for dc power.  
DTJL = qJL PD
