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.
