1. TOLERANCE AND TYPE NUMBER DESIGNATION
Tolerance designation - device tolerance of ±5% are indicated by a “5” suffix.
2. ZENER VOLTAGE (VZ) MEASUREMENT
ON Semiconductor guarantees the zener voltage when measured at 40 ms ±10 ms, 3/8″ from the diode body. And an ambient temperature
of 25°C (+8°C, -2°C)
3. ZENER IMPEDANCE (ZZ) DERIVATION
The zener impedance is derived from 60 seconds AC voltage, which results when an AC current having an rms value equal to 10% of the
DC zener current (IZT or IZK) is superimposed on IZT or IZK.
4. SURGE CURRENT (IR) NON-REPETITIVE
The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or
equivalent sine wave pulse of 1/120 second duration superimposed on the test current, IZT
, per JEDEC standards. However, actual device
capability is as described in Figure 3 of the General Data sheet for Surmetic 30s.
†The “G'' suffix indicates these are Pb-Free packages.

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 = qLA PD + TA
qLA is the lead‐to‐ambient thermal resistance (°C/W) and
PD is the power dissipation. The value for qLA will vary and
depends on the device mounting method. qLA is generally
30-40°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 + DTJL
DTJL 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.
DTJL = qJL PD
For worst‐case design, using expected limits of IZ, limits
of PD and the extremes of TJ (DTJ) may be estimated.
Changes in voltage, VZ, can then be found from:
DV = qVZ DTJ
qVZ, the zener voltage temperature coefficient, is found
from Figures 5 and 6.
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 2 should not be used to compute surge
capability. Surge limitations are given in Figure 3. 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 3 be exceeded.
