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, T

, should be determined from:

L

TL = qLA PD + T

A

qLA is the lead‐to‐ambient thermal resistance and PD is the

power dissipation.

Junction Temperature, T

, may be found from:

J

TJ = TL + DT

JL

DTJL 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 1 for dc power.

DTJL = qJL P

D

For worst‐case design, using expected limits of IZ, limits

and the extremes of TJ (DTJ) may be estimated.

of P

D

Changes in voltage, V

, can then be found from:

Z

DV = qVZ DT

J

qVZ, 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 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.
