DS9503

19-4699; 7/09 www.maxim-ic.com DS9503 ESD Protection Diode with Resistors SPECIAL FEATURES  Zener characteristic with voltage snap–back to protect against ESD hits  High avalanche voltage, low leakage and low capacitance avoid signal attenuation  Compatible to all 5V logic families  Space saving, low inductance TSOC surface mount package  On–chip 5resistors for isolation at both anode and cathode terminals  Industrial temperature range SYMBOL AND CONVENTIONS C IC VCA A PACKAGE OUTLINE TSOC SURFACE MOUNT PACKAGE 16 25 34 TOP VIEW SIDE VIEW ORDERING INFORMATION DS9503P+ 6-lead TSOC package DS9503P+T&R 6-lead TSOC package +Denotes a lead(Pb)-free/RoHS-compliant package. T&R = Tape and reel. 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 i...
