NOTE 1 - TOLERANCE AND VOLTAGE DESIGNATION
TOLERANCE DESIGNATION - The JEOEC type numbers shown
indicat. a tolerance of ±20% 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 "A" for ±10% tolerance and suffix "B" for ±5.0% units.
NOTE 2 - SPECIALS AVAILABLE INCLUDE:
IA) NOMINAL ZENER VOLTAGES BETWEEN THE VOLT·
AGES SHOWN AND TIGHTE R VOLTAGE TO LE RANCES:
To designate units with zener voltages other than those
assigned jEDEC numbers and/or tight voltage tolerances
1±3%, ±2%, ± 1%), the MfWI.. type number should be used.
5 M 90
IB) MATCHED SETS: IStandard Tolerances are ±5.O%, ±2.O%,
Zener diodes can be obtained in sets consisting of two or more
matched devices. The method for specifying such matched
sets is similar to the one described in (A) for specifying units
with a special voltage and/or tolerance except that two extra
suffixes are added to the code number described.
These units are marked with code letters to identify the
matched sets and, in addition, each unit in a set is marked
with the same serial number, which is different for each set

NOTE 3 - ZENER VOLTAGE (VZ) AND IMPEDANCE
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. ITA =250 C ~~ °CI.
NOTE 4 - SURGE CURRENT lir )
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 6 may be used to find the maximum
surge current for a square WfNe of any pulse width between 1.0
ms and 1000 ms by plotting the applicable points on logarithm ic
paper. Examples of this, using the 3.3 V and 200 V zeners, are
shown in Figure 7. Mounting contact located as soecified in
Note 3. ITA = 250 C ~~oC).
NOTE 5 - VOLTAGE REGULATION (L:>VZ)
Test conditions for voltage regulation are as follows: Vz meas-
urements 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 dur~tion for each Vz measurement is 40 ± 10 ms. (TA ==
25°C ~~ CI. Mounting contact located as specified in Note 3.
NOTE 6 - MAXIMUM REGULATOR CURRENT (lZM)
The maximum current shown is based on the maximum voltage
of a 5% type unit, therefore, it applies only to Jhe B-suffix
device. The actual IZM for any device may not exceed the
value of 5.0 watts divided by the actual Vz of the device.
T L == 75°C at 3/8" maximum from the device body.
