1.
TOLERANCE AND TYPE NUMBER DESIGNATION
The type numbers listed have zener voltage min/max limits as shown and have a standard tolerance on the nominal zener voltage of
±5%.
2.
AVAILABILITY OF SPECIAL DIODES
For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter voltage
tolerances, contact your nearest ON Semiconductor representative.
3.
ZENER VOLTAGE (V
Z
) MEASUREMENT
V
Z
measured after the test current has been applied to 40
±10
msec, while maintaining the lead temperature (T
L
) at 30°C
±1°C,
3/8″ from
the diode body.
4.
ZENER IMPEDANCE (Z
Z
) DERIVATION
The zener impedance is derived from 1 kHz 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
.
5.
SURGE CURRENT (I
R
) NON–REPETITIVE
The rating listed in the electrical characteristics table is maximum peak, non–repetitive, reverse surge current of 1/2 square wave or eqivalent
sine wave pulse of 1/120 second duration superimposed on the test current, I
ZT
. However, actual device capability is as described in Figure
5 of the General Data – DO–41 Glass.
