NOTE:
1. Tolerance and Type Number Designation. The type numbers listed have a standard tolerance on the nominal zener voltage of ±5%.
2. Specials Available Include:
A. Nominal zener voltages between the voltages shown and tighter voltage tolerances.
B. Matched sets.
3. Zener Voltage (V
Z
) Measurement. Guarantees the zener voltage when measured at 90 seconds while maintaining the lead temperature (T
L
) at 30
O
C, from the diode body.
4. Zener Impedance (Z
Z
) Derivation. 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
.
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 equivalent 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.
