NOTE:

1. TOLERANCE AND VOLTAGE DESIGNATION - The JEDEC type numbers shown indicate a tolerance of ¡Ó 10% with
guaranteed limits on only Vz, IR, Ir, and VF as shown in the electrical characteristics table. Units with guaranteed

limits on all seven parameters are indicated by suffix “B” for ¡Ó5% tolerance.

2. ZENER VOLTAGE (Vz) AND IMPEDANCE (ZZT & ZZK) - Test conditions for Zener voltage and impedance are as
follows; Iz is applied 40 ¡Ó 10 ms prior to reading. Mounting contacts are located from the inside edge of mounting
clips to the body of the diode.(TA=25 ¢J

¡Ï¢·
¡Ð¢±

¢J).

SMCJ5348 thru SMCJ5388

3. SURGE CURRENT (Ir) - Surge current is specified as the maximum allowable peak, non-recurrent square-wave
current with a pulse width, PW, of 8.3 ms. The data given in Figure 5 may be used to find the maximum surge
current for a quare wave of any pulse width between 1 ms and 1000ms by plotting the applicable points on
logarithmic paper. Examples of this, using the 6.8v and 200V zeners, are shown in Figure 6. Mounting

contact located as specified in Note 3. (TA=25 ¢J

4. VOLTAGE REGULATION (£GVz) - 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 currents are the

same for the 5% and 10% tolerance devices. The test current time druation for each Vz measurement is 40 ¡Ó 10 ms.
(TA=25 ¢J

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 ¢J at maximum from the device body.

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 = £cLAPD + T

£c

and PD is the power dissipation.
Junction T emperature, TJ , may be found from:

£GTJL is the increase in junction temperature above the
lead temperature and may be found from Figure 3 for
a train of power pulses or from Figure 4 for dc power.

For worst-case design, using expected limits of Iz, limits

is the lead-to-ambient thermal resistance (¢J/W)

TJ = TL + £GT

£GT

JL

D

of PD and the extremes of TJ(£GTJ) may be estimated.
Changes in voltage, Vz, can then be found from:

£GV = £cVZ£GT

£c

, the zener voltage temperature coefficient, is fount

VZ

from Figures 2.
Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly be
the zener resistance. For best regulation, keep current
excursions as low as possible.
Data of Figure 3 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.
