package
On–chip 5
resistors for isolation at both anode and
cathode terminals
Industrial temperature range
DESCRIPTION
This DS9503 is designed as an ESD protection device
for 1–Wire MicroLAN interfaces. In contrast to the
DS9502, the DS9503 includes two 5
isolation resis-
tors on chip. Although 5
are negligible during commu-
nication, they represent a high impedance relative to the
conducting diode during an ESD event. Thus, the diode
absorbs the energy while the resistors further isolate
and protect the circuit at the other side of the package. If
used with circuits that already have a strong ESD–
protection at their I/O port, the ESD protection level is
raised to more that 27 kV (IEC 801–2 Reference model).
In case of abnormal ESD hits beyond its maximum rat-
ings the DS9503 will eventually fail “short” thus prevent-
ing further damage.
During normal operation the DS9503 behaves like a
regular 7.5V Zener Diode. When the voltage exceeds
the trigger voltage, the I/V characteristic of the device
will “snapback” allowing the same or higher amount of
current to flow, but at a significantly lower voltage. As
long as a minimum current or voltage is maintained, the
device will stay in the “snapback mode”. If the voltage or
the current falls below the holding voltage or holding
current, the device will abruptly change to its normal
mode and conduct only a small leakage current.
