NOTES:
1. TOLERANCES - Suffix indicates 5% tolerance any other tolerance will be considered as a special device.
2. ZENER VOLTAGE (Vz) MEASUREMENT - guarantees the zener voltage when measured at 40 ms
¡Ó
10ms
from the diode body, and an ambient temperature of 25
¢J
(
¡Ï
8
¢J
, -2
¢J
).
3.ZENER IMPEDANCE (Zz) DERIVATION - The zener impedance is derived from the 60 cycle ac voltage,
which results when an ac current having an rms falue equal to 10% of the dc zener current (I
ZT
or I
ZK
) is
superimposed on I
ZT
or I
ZK
.
4. SURGE CURRENT (Ir) NON-REPETITIVE - The rating listed in the electrical characteristics table is
maximum peak, non-repetitive, reverse surge current of 1/2 square wave or equivalent sine wave pulse
of 1/120 second duration superimposed on the test current, I
ZT
, per JEDEC standards, however, actual
device capability is as described in Figure 3.
