1. TOLERANCE AND TYPE NUMBER DESIGNATION
The JEDEC type numbers shown indicate a tolerance of ±5%.
2. ZENER VOLTAGE (VZ) and IMPEDANCE (IZT and IZK)
Test conditions for zener voltage and impedance are as follows: IZ is applied 40 ±10 ms prior to reading. Mounting contacts are located 3/8″
to 1/2″ from the inside edge of mounting clips to the body of the diode (TA = 25°C +8°C, –2°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 6 may be used to find the maximum surge current for a square wave of any pulse width between 1 ms and 1000 ms by plotting
the applicable points on logarithmic paper. Examples of this, using the 3.3 V and 200 V zener are shown in Figure 7. Mounting contact located
as specified in Note 2 (TA = 25°C +8°C, –2°C).
4. VOLTAGE REGULATION (VZ)
The 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 current time duration for each VZ measurement is 40 ±10 ms. Mounting contact located as specified
in Note 2 (TA = 25°C +8°C, –2°C).
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 = 75°C at 3/8″ 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, TL, should be determined from:
For worst-case design, using expected limits of IZ, limits
of PD and the extremes of TJ (∆TJ) may be estimated.
Changes in voltage, VZ, can then be found from:
∆V = θVZ ∆TJ
θVZ, 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 6. 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 6 be exceeded.
TL = θLA PD + TA
θLA is the lead-to-ambient thermal resistance and PD is the
power dissipation.
Junction Temperature, TJ, may be found from:
TJ = TL + ∆TJL
∆TJL 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 5 for dc power.
∆TJL = θJL PD
