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:
TJ = TL + ∆TJL.
∆TJL is the increase in junction temperature above the lead
temperature and may be found from Figure 2 for dc power:
∆TJL = θJLPD.
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.

NOTE 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 400 milliwatts divided by the actual VZ of the device.

∆VZ is the maximum difference between VZ at IZT and VZ at IZL measured with the device
junction in thermal equilibrium.

GENERAL DATA — 500 mW DO-35 GLASS
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:
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:
TJ = TL + ∆TJL.
∆TJL is the increase in junction temperature above the lead
temperature and may be found as follows:
∆TJL = θJLPD.
θJL may be determined from Figure 3 for dc power condi-
tions. 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
Figure 2.
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 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.

The JEDEC type numbers shown indicate a tolerance of ±5%.
NOTE 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 3/8″ to 1/2″ from the inside edge of mounting clips
to the body of the diode. (TA = 25°C +8, –2°C).
NOTE 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 1ms and 1000 ms by
plotting the applicable points on logarithmic paper. Examples of this, using the 3.3 V and
200 V zeners, are shown in Figure 7. Mounting contact located as specified in Note 3. (TA =
25°C +8, –2°C.)
NOTE 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 current
time duration for each VZ measurement is 40 ± 10 ms. (TA = 25°C +8, –2°C). Mounting contact
located as specified in Note 2.
NOTE 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.
NOTE 6. SPECIALS AVAILABLE INCLUDE:
Nominal zener voltages between the voltages shown and tighter voltage tolerance such as
±1% and ±2%. Consult factory.

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:
TL = θLA PD + T
θLA is the lead-to-ambient thermal resistance and PD is the
power dissipation.
Junction Temperature, TJ, may be found from:
TJ = TL + ∆T
∆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 P

Figure 10. Zener V oltage versus Zener Current
VZ = 82 thru 200 V olts
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 ∆T
J
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.
