Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc-
tiontemperatureunderanysetofoperatingconditionsinorder
to calculate its value. The following procedure is recom-

The temperature of the lead can also be measured using a
thermocoupleplacedontheleadascloseaspossibletothetie
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-

Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly by the
zenerresistance. Forbestregulation, keepcurrentexcursions
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 ex-
tremely high in small spots, resulting in device degradation
should the limits of Figure 7 be exceeded.

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 pow-

APPLICATION NOTE
Since the actual voltage available from a given zener diode
temperature and may be found as follows:
is temperature dependent, it is necessary to determine junc-
tiontemperatureunderanysetofoperatingconditionsinorder
to calculate its value. The following procedure is recom-
mended:
∆T = θ P .

Under high power-pulse operation, the zener voltage will

vary with time and may also be affected significantly by the
zenerresistance. Forbestregulation, keepcurrentexcursions
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.
The temperature of the lead can also be measured using a
thermocoupleplacedontheleadascloseaspossibletothetie
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 T , the junction temperature may be deter-
L
mined by:
T = T + ∆T .

NOTE 1. TOLERANCE AND TYPE NUMBER DESIGNATION
NOTE 4. ZENER IMPEDANCE (Z ) DERIVATION
Z
The JEDEC type numbers listed have a standard tolerance on the nominal zener voltage of
±5%. C for ±2%, D for ±1%.
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 (I or I ) is superimposed

on I or I

NOTE 2. SPECIALS AVAILABLE INCLUDE:
Nominal zener voltages between the voltages shown and tighter voltage tolerances.
For detailed information on price, availability, and delivery, contactyournearestMotorolarep-

NOTE 5. SURGE CURRENT (i ) NON-REPETITIVE
r
The rating listed in the electrical characteristics table is maximum peak, non-repetitive, re-

NOTE 3. ZENER VOLTAGE (V ) MEASUREMENT
Z
Motorola guarantees the zener voltage when measured at 90 seconds while maintaining the

APPLICATION NOTE
Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc-
tiontemperatureunderanysetofoperatingconditionsinorder
to calculate its value. The following procedure is recom-
mended:
∆T is the increase in junction temperature above the lead
temperature and may be found from Figure 2 for a train of
power pulses (L = 3/8 inch) or from Figure 10 for dc power.

use and for printed circuit board wiring.
Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly by the
zenerresistance. Forbestregulation, keepcurrentexcursions
as low as possible.
Data of Figure 2 should not be used to compute surge capa-
bility. Surge limitations are given in Figure 3. They are lower
than would be expected by considering only junction tempera-
ture, as current crowding effects cause temperatures to be ex-
tremely high in small spots resulting in device degradation
should the limits of Figure 3 be exceeded.
The temperature of the lead can also be measured using a
thermocoupleplacedontheleadascloseaspossibletothetie
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 T , the junction temperature may be deter-

mined by:

Motorola guarantees the zener voltage when measured at 40 ms ±10 ms 3/8″ from the diode

APPLICATION NOTE
Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc-
tiontemperatureunderanysetofoperatingconditionsinorder
to calculate its value. The following procedure is recom-
mended:
For worst-case design, using expected limits of I , limits of
Z
P
and the extremes of T (∆T ) may be estimated. Changes
J J
D
in voltage, V , can then be found from:
Z
∆V = θ
∆T
J
VZ
θ
,thezenervoltagetemperaturecoefficient,isfoundfrom
VZ
Lead Temperature, T , should be determined from:
L
Figures 2 and 3.
T = θ
P
+ T
A
L
LA
D
Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly by the
zenerresistance. Forbestregulation, keepcurrentexcursions
as low as possible.
θ
is the lead-to-ambient thermal resistance and P is the
LA
power dissipation.
D
Junction Temperature, T , may be found from:
J
T = T + ∆T
JL
Data of Figure 4 should not be used to compute surge capa-
bility. Surge limitations are given in Figure 6. They are lower
than would be expected by considering only junction tempera-
ture, as current crowding effects cause temperatures to be ex-
tremely high in small spots resulting in device degradation
should the limits of Figure 6 be exceeded.
J
L
∆T 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.
