TOLERANCE AND TYPE NUMBER DESIGNATION
Tolerance designation
−
device tolerance of
±5%
are indicated by a “5” suffix.
2.
ZENER VOLTAGE (V
Z
) MEASUREMENT
ON Semiconductor guarantees the zener voltage when measured at 40 ms
±10
ms, 3/8″ from the diode body. And an ambient temperature
of 25°C (+8°C,
−2°C)
3.
ZENER IMPEDANCE (Z
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.
