Product Summary

This DS9503P+ is designed as an ESD protection device for 1–Wire MicroLAN interfaces. In contrast to the DS9502, the DS9503P+ includes two 5W isolation resistors on chip. Although 5Ω 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 DS9503P+ will eventually fail “short” thus preventing further damage.

Parametrics

Absolute maximum ratings: (1)Operating Temperature: –40℃ to +85℃; (2)Storage Temperature: –55℃ to +125℃; (3)Soldering Temperature: 260℃ for 10 seconds; (4)Continuous DC Current Through Package: 80 mA.

Features

Features: (1)Zener characteristic with voltage snap–back to protect against ESD hits; (2)High avalanche voltage, low leakage and low capacitance avoid signal attenuation; (3)Compatible to all 5V logic families; (4)Space saving, low inductance TSOC surface mount package; (5)On–chip 5Ω resistors for isolation at both anode and cathode terminals; (6)Industrial temperature range.
