5 Watt Surmetic 40
Silicon Zener Diodes
This is a complete series of 5 Watt Zener Diodes with tight limits and better operating
characteristics that reflect the superior capabilities of silicon-oxide-passivated junctions.
All this is in an axial-lead, transfer-molded plastic package that offers protection in all com-
mon environmental conditions.

NOTE 1. TOLERANCE AND TYPE NUMBER DESIGNATION
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 cur-
rent 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 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 =
LA PD + TA
LA is the lead-to-ambient thermal resistance and PD is the
power dissipation.
Junction Temperature, TJ, may be found from:
TJ = TL +
TJL
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 =
JL PD
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
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 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.
