TOLERANCE AND TYPE NUMBER DESIGNATION
2. The JEDEC type numbers listed have a standard tolerance on the nominal zener voltage of
±
5%.
SPECIALS AVAILABLE INCLUDE:
3. Nominal zener voltages between the voltages shown and tighter voltage tolerances. For detailed information on price, availability, and
delivery, contact your nearest ON Semiconductor representative.
ZENER VOLTAGE (V
Z
) MEASUREMENT
4. ON Semiconductor guarantees the zener voltage when measured at 90 seconds while maintaining the lead temperature (T
L
) at 30
°
C
±
1
°
C, 3/8
″
from the diode body.
ZENER IMPEDANCE (Z
Z
) DERIVATION
5. The zener impedance is derived from the 60 cycle ac voltage, which results when an ac current having an rms value equal to 10% of the
dc zener current (I
ZT
or I
ZK
) is superimposed on I
ZT
or I
ZK
.
SURGE CURRENT (I
R
) NON-REPETITIVE
6. The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or equiv-
alent sine wave pulse of 1/120 second duration superimposed on the test current, I
ZT
, per JEDEC registration; however, actual device
capability is as described in Figure 5 of the General Data — DO-41 Glass.
