DS9503P

DS9503P
ESD Protection Diode with Resistors, 1-Wire, TSOC6, Maxim, RoHS

---

This DS9503 is designed for ESD protection device for 1-Wire MicroLAN interfaces. In contrast to the DS9502, the DS9503 includes two 5 Ohm isolation resistors on chip. Although 5 Ohm are negligible during communication, they represent a high impedance to the diode during an ESD event. Thus, the diode absorbs the other side of the package. If it has a more than 27 kV (IEC 801-2 Reference model) ESD-protection at their I / O port, the ESD protection. In case of abnormal, the ESD hits above its maximum ratings. DS9503 will eventually fail "short" so no further damage.

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 Ohms resistors for isolation at both anode and cathode terminals
• Industrial temperature range
