ORDERING INFORMATION

DS9503P+

DS9503P+T&R

+Denotes a lead(Pb)-free/RoHS-compliant package.

T&R = Tape and reel.

6-lead TSOC package

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 resistors on chip. Although 5are negligible during

communication, 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 ratings the DS9503 will eventually fail “short” thus preventing further

damage.

During normal operation the DS9503 behaves like a regular 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.
