DS9503 ESD Protection Diode with Resistors

This DS9503 is designed as an ESD protection device for 1 *Wire MicroLAN interfaces. In contrast to the DS9502, the DS9503 includes two 5Ω isolation resistors on chip. Although 5Ω are negligible during communication, they represent a high impedance relative to the conducting diode during an E.

DS9503 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 SYMBOL AND CONVENTIONS
