DS9503 Description
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 munication, they represent a high impedance relative to the conducting diode during an ESD event.
DS9503 Key Features
- Zener characteristic with voltage snap-back to protect against ESD hits
- High avalanche voltage, low leakage and low capacitance avoid signal attenuation
- patible to all 5V logic families
- Space saving, low inductance TSOC surface mount package
- On-chip 5Ω resistors for isolation at both anode and cathode terminals
- Industrial temperature range
