Product Overview

The DS9503P+T&R is a ESD protection diode with resistors in 6 pin TSOC package. It is designed as an ESD protection device for 1-wire MicroLAN interfaces, in contrast to DS9502, DS9503 includes two 5ohm isolation resistors on chip. Although 5ohm is negligible during communication, it represent a high impedance relative to the conducting diode during an ESD event. Thus, diode absorbs energy while resistors further isolate and protect circuit at other side of 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 27KV (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.
  • Avalanche voltage range from 7.4V to 11.05V
  • Maximum trigger voltage is 11V, maximum triggered current is 1000mA
  • Maximum continuous current through diode is ±80mA
  • Junction to package thermal resistance is 75K/W at tA=25°C, junction to ambient is 200K/W at tA=25°C
  • Maximum peak current is 2A
  • 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 surface mount package
  • Industrial temperature range of -40°C to +85°C
