APPLICATION NOTE
Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc-
tion temperature under any set of operating conditions in order
to calculate its value. The following procedure is recom-
mended:
Lead Temperature, TL, should be determined from:
TL =
LAPD + TA.
LA is the lead-to-ambient thermal resistance (
C/W) and PD is
the power dissipation. The value for
LA will vary and depends
on the device mounting method.
LA 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 mea-
sured value of TL, the junction temperature may be deter-
mined by:
TJ = TL +
TJL.
TJL is the increase in junction temperature above the lead
temperature and may be found as follows:
TJL =
JLPD.
JL 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 =
VZ
TJ.
VZ, 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 ex-
tremely high in small spots, resulting in device degradation
should the limits of Figure 5 be exceeded.

NOTE 1. TOLERANCE AND TYPE NUMBER DESIGNATION
The JEDEC type numbers listed have a standard tolerance on the nominal zener voltage of
5%. C for
2%, D for
1%.
NOTE 2. SPECIALS AVAILABLE INCLUDE:
Nominal zener voltages between the voltages shown and tighter voltage tolerances.
For detailed information on price, availability, and delivery, contact your nearest Motorola rep-
resentative.
NOTE 3. ZENER VOLTAGE (VZ) MEASUREMENT
Motorola guarantees the zener voltage when measured at 90 seconds while maintaining the
lead temperature (TL) at 30
C

C, 3/8
from the diode body.
NOTE 4. ZENER IMPEDANCE (ZZ) DERIVATION
The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-
rent having an rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed
on IZT or IZK.
NOTE 5. SURGE CURRENT (ir) NON-REPETITIVE
The rating listed in the electrical characteristics table is maximum peak, non-repetitive, re-
verse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second dura-
tion superimposed on the test current, IZT, per JEDEC registration; however, actual device
capability is as described in Figure 5 of the General Data -- DO-41 Glass.

NOTE 1. TOLERANCE AND TYPE NUMBER DESIGNATION
The type numbers listed have zener voltage min/max limits as shown. Device tolerance of
2% are indicated by a "B" instead of "C."
NOTE 2. SPECIALS AVAILABLE INCLUDE:
Nominal zener voltages between the voltages shown and tighter voltage tolerances.
For detailed information on price, availability, and delivery, contact your nearest Motorola rep-
resentative.
NOTE 3. ZENER VOLTAGE (VZ) MEASUREMENT
VZ is measured after the test current has been applied to 40
10 msec., while maintaining
the lead temperature (TL) at 30
C
1
C, 3/8
from the diode body.
NOTE 4. ZENER IMPEDANCE (ZZ) DERIVATION
The zener impedance is derived from the 1 kHz cycle ac voltage, which results when an ac
current having an rms value equal to 10% of the dc zener current (IZT) or (IZK) is superim-
posed on IZT or IZK.
NOTE 5. SURGE CURRENT (ir) NON-REPETITIVE
The rating listed in the electrical characteristics table is maximum peak, non-repetitive, re-
verse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second dura-
tion superimposed on the test current IZT. However, actual device capability is as described
in Figure 5 of General Data DO-41 glass.
