2. TOLERANCE AND VOLTAGE DESIGNATION
Tolerance designation – the type numbers listed have zener voltage min/max limits as shown. Device tolerance of ±2% are indicated by a
“B” instead of a “C”. Zener voltage is measured with the device junction in thermal equilibrium at the lead temperature of 30°C ±1°C and 3/8″
lead length.
3. This data was calculated using nominal voltages. The maximum current handling capability on a worst case basis is limited by the actual
zener voltage at the operating point and the powered derating curve.
4. ZZT and ZZK are measured by dividing the ac voltage drop across the device by the ac current applied. The specified limits are for I Z(ac) =
0.1 IZ(dc) with the ac frequency = 1.0 kHz.

APPLICATION NOTE — ZENER VOLTAGE
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:
TL = θLAPD + TA.
θLA is the lead-to-ambient thermal resistance (°C/W) and PD
is the power dissipation. The value for θLA will vary and
depends on the device mounting method. θLA is generally 30
to 40°C/W for the various clips and tie points in common use
and for printed circuit board wiring.
The temperature of the lead can also be measured using a
thermocouple placed on the lead as close as possible to the
tie point. The thermal mass connected to the tie point is
normally large enough so that it will not significantly
respond to heat surges generated in the diode as a result of
pulsed operation once steady-state conditions are achieved.
Using the measured value of TL, the junction temperature
may be determined by:

∆TJL is the increase in junction temperature above the lead
temperature and may be found from Figure 2 for dc power:
200
∆TJL = θJLPD.
I R , LEAKAGE CURRENT ( µ A)
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 = θVZTJ.
θVZ, the zener voltage temperature coefficient, is found
from Figures 4 and 5.
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.
Surge limitations are given in Figure 7. 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 7 be exceeded.
