1.
TOLERANCE AND TYPE NUMBER DESIGNATION
The type numbers listed have a standard tolerance on the nominal zener voltage of
±
5%.
2.
ZENER VOLTAGE (V
) MEASUREMENT
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.
3.
ZENER IMPEDANCE (Z
) DERIVATION
The zener impedance is derived from 60 seconds 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
.
4.
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 standards. However, actual device
capability is as described in Figure 3 of the General Data sheet for Surmetic 30s.
